    Abstract

    Purpose The purpose of the study was to examine thecombined interactive effects of a situational variable

    (procedural justice) and a dispositional (equity sensitivity)

    variable on the relationship between breach and employee

    outcomes.

    Design/methodology/approach Data were obtained from

    403 full-time employees representing a wide variety of

    business sectors in the Philippines. Supervisors were

    requested to provide an assessment of their subordinates

    civic virtue behavior.

    Findings Results showed that equity sensitivity and

    breach interacted in predicting affective commitment. The

    negative relationship between breach and affective com-

    mitment was stronger for employees with an input-focused

    approach to organizational relationships (referred to as

    benevolents) than for those with an outcome-focused

    approach (referred to as entitleds). Results also indicated a

    stronger negative relationship between contract breach and

    civic virtue behavior under conditions of high procedural

    justice. Finally, a three-way interaction was found between

    contract breach, procedural justice and equity sensitivity in

    predicting affective commitment.Implications Our findings provide a new insight sug-

    gesting that worse outcomes are to be anticipated

    especially if employees have an expectation that procedural

    justice can prevent any form of contract breach. In addi-

    tion, although previous research has portrayed benevolents

    as more accepting of situations of u under-reward, this

    study has demonstrated that they too have their limits or

    threshold for under-reward situations.

    Originality/value This research suggests that the type and

    intensity of ones reactions to psychological contract

    breach is influenced by interactive forces of the individ-

    uals disposition and the organizational procedures.

    Introduction

    Psychological contract breach takes place when one party

    in a relationship perceives that the other party has

    neglected to fulfill what has been committed or promised

    (Rousseau 1995). For example, employees may believe

    that the organization is obliged to give career growth

    opportunities. If the organization does not provide the

    career growth opportunities, it results in a contract breach.

    The effect of breach is explained by the social exchange

    theory (SET) which proposes that when one party provides

    something to another, it expects the other party to recip-

    rocate by providing some contributions in return (Blau

    1964). Previous research on psychological contracts has

    primarily focused on three areas. The first line of research

    the academy of management meeting, New Orleans, USA, August,

    2004.

    has examined the consequences of psychological contract

    breach on a wide range of employee behaviors (e.g., job

    performance, citizenship behavior; Turnley et al. 2003;

    Restubog and Bordia 2006; Restubog et al. 2006; Robinson

    and Morrison 1995) and attitudes (e.g., commitment, sat-

    isfaction, and turn-over intentions; Kickul and Lester 2001;

    Restubog and Bordia 2006; Restubog et al. 2006; Turnley

    and Feldman 1999). These studies suggest that employeesare likely to withdraw from performing discretionary

    behaviors and demonstrate negative attitudes as a way of

    responding to contract breach. Another line of research has

    investigated situational factors which are likely to influence

    the relationship between breach and employee outcomes

    (e.g., Kickul et al. 2002). For example, procedural and

    interactional justice reduces the negative impact of psy-

    chological contract breach on employee behaviors (Kickul

    et al. 2002). Finally, an emerging line of research concerns

    the role of dispositional characteristics in the psychological

    contract process. As the formation and maintenance of

    psychological contracts emerge from an idiosyncraticbelief (Rousseau 1995) and result from a cognitive

    appraisal (Morrison and Robinson 1997), dispositional

    characteristics are likely to be an important element in the

    contract-making dynamics.

    The present study builds upon previous research on

    psychological contracts in two ways. First, it systematically

    examines the combined-interactive effects of a situational

    variable (procedural justice) and a dispositional character-

    istic (equity sensitivity) on the breach-employee outcomes

    relationship. Most of the research undertaken in the area of

    psychological contracts has emphasized situational moder-

    ators (i.e., organizational justice), while emerging research

    focuses on the role of individual differences in predicting

    responses to breach (i.e., equity sensitivity). While

    researchers have noted that both situational and personal

    characteristics contribute to our understanding of work

    attitudes and behaviors (Schneider 1983; Terborg 1981),

    none of the studies in the psychological contracts literature

    empirically tested the moderating role of both situational

    and personal characteristics in a single study. The present

    study fills this gap by examining the possibility of a person

    through situation interaction simultaneously considering

    these two classes of variables. Our approach in examining

    how procedural justice (a situational variable) and equity

    sensitivity (a dispositional variable) influence the breach-

    outcomes relationship is firmly embedded in an interac-

    tionist perspective (Schneider 1983; Terborg 1981) which

    incorporates the multi-directional interaction between

    person characteristics and situation characteristics

    (Terborg 1981, p. 569).

    Several researchers, in fact, have highlighted the need

    for an interactionist approach in psychological contract

    research (Coyle-Shapiro and Neuman 2004; Turnley and

    Feldman 1999). In the organizational justice literature,

    Cropanzano noted that justice rests in the eyes of the

    beholder (in Coyle-Shapiro and Neuman 2004, p. 153). In

    other words, perceptions of justice may be influenced by

    individual dispositions or personality traits. Thus, in order

    to gain a better understanding of the psychological contract

    dynamics, researchers are also encouraged to consider what

    individuals bring into the situation.Second, most previous research on psychological con-

    tract breach has been conducted in western countries (with

    the exception of Hui et al. 2004) where cultures are typically

    individualist and low in power distance (Hofstede 1997). As

    a result of this, limited attention has been given to the

    generalizability of the psychological contract framework in

    cultures with a more collectivistic orientation or high-power

    distance. Rousseau and Schalk (2000) pointed out that little

    is known about how culture affects the meanings and

    interpretations ascribed to psychological contracts and how

    employees and organizations from different societies eval-

    uate the extent to which the psychological contract has beenmet or violated. There is also a tendency in research to judge

    all collectivist and high-power distant cultures as similar to

    each other (Kim and Leung 2007). While several Asian

    cultures are collectivist and have high-power distance,

    individual national cultures display other cultural elements

    in the workplace. In Philippines, along with the prevalence

    of high-power distance (Hofstede 1997), workplace fami-

    lism is also an important part of the organizational culture

    (Restubog and Bordia 2006, 2007). In contexts marked by

    high workplace familism, employees see the organization as

    a symbolic representation of a family and expect nurturance,

    loyalty and compassion from the organization. Therefore, a

    subordinatesupervisor relationship will be seen as a par-

    allel of a parentchild relationship (Hofstede 1997;

    Restubog and Bordia 2007). Workplace familism is also

    related to the notion of high-power distance. As in a parent

    child relationship, the supervisorsubordinate relationship

    constitutes a difference in power status (even when the

    relationship is a positive one). Considering that not all Asian

    cultures are similar, this study allows an investigation of the

    consequences of psychological contract breach specifically

    in the Philippines context. We begin by reviewing the

    literature on consequences of contract breach and develop

    hypotheses on the impact of breach on affective commit-

    ment and civic virtue behavior. Next, we present procedural

    justice and equity sensitivity as moderators influencing the

    relationship between breach and these employee outcomes.

    Organizational Commitment

    Organizational commitment reflects the psychological

    bond between employees and their organization (Allen and

    Meyer 1990). The dimension of commitment, we consider

    166 J Bus Psychol (2009) 24:165178

    123

    most relevant in this research is affective commitment

    which refers to an emotional response and orientation that

    links the individual to the organization (Allen and Meyer

    1990). From a social exchange perspective (Blau 1964), it

    can be argued that when the organization is perceived to

    inadequately fulfill its commitments, employees will view

    their social exchange with the organization as less valu-

    able. As a result, employees will reciprocate by decreasingtheir affective commitment to the organization (e.g.,

    Bunderson 2001; Turnley and Feldman 1999). We expect

    that fulfillment of the psychological contract-related obli-

    gations will be reciprocated by employees in the form of

    commitment to the organization. Previous studies suggest

    that the extent to which an employees psychological

    contract has been fulfilled has a significant bearing on

    affective commitment (Bunderson 2001). In contrast, in

    the case of a psychological contract breach, employees

    perceiving the organization to not meet its obligations may

    choose to rectify the imbalance by lowering their sense of

    commitment towards the organization (Rousseau 1995).Conway and Briner (2002) found that the effect of breach

    on employees affective commitment is similar regardless

    of their work status (full- or part-time). Based on the

    consistency in findings regarding the relationship between

    breach and affective commitment, we predict that psy-

    chological contract breach will reduce employees

    affective commitment.

    Hypothesis 1 Psychological contract breach will be

    negatively related to affective commitment.

    Organizational Citizenship Behaviors

    Organizational citizenship behaviors (OCBs) relate to

    employee behaviors that are not part of the core job

    description but facilitate the overall effectiveness of the

    organization (Podsakoff et al. 2000). Therefore, OCBs

    comprises of actions that individuals may take, at their own

    discretion, to create a psychologically and socially sup-

    portive environment in the workplace (Blakely et al. 2003,

    2005). OCBs have been conceptualized as comprising of

    five key dimensions: altruism, civic virtue, conscientious-

    ness, courtesy, and sportsmanship (Podsakoff et al. 2000).

    In the current study, we focus on civic virtue behaviors as itis clearly directed towards the organization and is more

    affected compared to OCBs directed towards co-workers

    whenever, there is a perceived contract breach (Robinson

    and Morrison 1995; Turnley et al. 2003). Civic virtue

    behavior is demonstrated in active participation in orga-

    nizational activities, keeping up with the changes affecting

    the organization, and being concerned with the welfare of

    the organization and its members (Podsakoff et al. 2000).

    These behaviors reflect a general interest, responsible

    involvement, and consideration in the affairs of the

    organization.

    Previous research suggests that OCBs can be negatively

    influenced by failure on the part of the organization to ade-

    quately fulfill the psychological contract of its employees.

    For example, employees whose psychological contracts

    were not fulfilled by their employers were less likely to

    demonstrate civic virtue behaviors (Restubog and Bordia2006; Robinson and Morrison 1995). A large majority of

    research supports the relationship between breach and OCBs

    (Robinson and Morrison 1995; Turnley et al. 2003). Draw-

    ing from SET and the norm of reciprocity, when employees

    feel that the organization has fulfilled its obligations towards

    them, they will reciprocate by helping their organization.

    Conversely, when employees feel that their organization has

    failed to provide what is due to them, they will reciprocate

    by performing only their required responsibilities and

    reducing civic virtue behaviors. Therefore, based on the

    literature, we predict that psychological contract breach will

    be negatively related to civic virtue behavior.

    Hypothesis 2 Psychological contract breach will be

    negatively related to civic virtue behavior.

    Procedural Justice

    Employees perception of justice within the organizational

    system affects their attitudes and behavior towards the

    organization (Blakely et al. 2005; Kim and Leung 2007).

    Among the three facets of justice that have been examined

    in the organizational literature (distributive, procedural and

    interactional), procedural justice refers to the fairness in theprocess by which outcomes such as promotions or bud-

    getary allocations are made (Cohen and Spector 2001).

    Employees responses to management decisions are

    strongly influenced by the perceived fairness of procedures

    and rules (Cohen and Spector 2001). Procedural justice is

    likely to have a direct and moderating effect. That is,

    procedural justice increases the likelihood of positive

    employee outcomes. A climate of procedural justice has

    been found to foster organizational commitment and citi-

    zenship behavior (Liao and Rupp 2005). Perceptions of

    procedural justice induce trust in management and satis-

    faction with performance appraisal system (Cropanzanoet al. 2002). Rifai (2005) found that procedural justice

    affects job satisfaction which affects organizational citi-

    zenship behavior via affective commitment. More compre-

    hensively, recent meta-analytic studies found a positive

    relationship between employees perceptions of procedural

    justice and work performance, job satisfaction, OCBs,

    affective commitment, and trust in the organization (Cohen

    and Spector 2001; Colquitt et al. 2001). Based on this

    research, we predict that procedural justice will be

    positively related to affective commitment and civic virtue

    behavior.

    Hypothesis 3 Procedural justice will be positively related

    to affective commitment.

    Hypothesis 4 Procedural justice will be positively related

    to civic virtue behavior.

    Procedural justice may also play a moderating role in

    the relationship between psychological contract breach and

    employee outcomes. Empirical evidence suggests that

    individuals responses to unfavorable actions are less

    severe when they perceive the decision-making process to

    be procedurally just (Brockner et al. 1990). For example,

    Turnley and Feldman (1999) found that procedural justice

    moderated the relationship between breach and exit such

    that employees were most likely to stay in their organiza-

    tion when the magnitude of breach was low and procedural

    justice was perceived to be high. Kickul et al. (2002) found

    similar moderating effects. In particular, they found higherjob satisfaction, in-role performance, and OCBs and lower

    intentions to leave when procedural justice was perceived

    to be high. These results suggest that fair treatment can

    mitigate the negative responses of employees who have

    experienced a contract breach. Procedural justice, there-

    fore, can control the negative effects of breach and makes

    its impact on employee outcomes less harmful.

    In the context of the current research, affective com-

    mitment and civic virtue behavior could be considered as

    employee inputs or contributions. Thus, when employees

    perceive that their psychological contract has been brea-

    ched, their willingness to reciprocate by under-performingor withholding behaviors beneficial to their organization

    will depend on whether they perceive organizational

    processes and procedures to be fair. Based on the litera-

    ture reviewed, we expect that under conditions of high-

    procedural justice, the negative impact of breach of

    psychological contract will be mitigated.

    Hypothesis 5 Procedural justice will moderate the rela-

    tionship between psychological contract breach and

    affective commitment. The consequences of breach will be

    worse when procedural justice is low compared to when it

    is high.

    Hypothesis 6 Procedural justice will moderate the rela-

    tionship between psychological contract breach and civic

    virtue behavior. The consequences of breach will be worse

    when procedural justice is low compared to when it is high.

    Equity Sensitivity

    Equity sensitivity is an individual difference variable

    which concerns peoples preferences for different input/

    outcome relations (Huseman et al. 1985, 1987). Given that

    psychological contract breach involves an assessment of

    unfair distribution of outcomes, equity sensitivity is likely

    to influence reactions to breach. Huseman et al. (1985,

    1987) classified three types of individuals along a contin-

    uum, each showing different orientation towards equity. At

    one end of the continuum is the benevolents. These are

    individuals who prefer their inputs to exceed their out-puts (Huseman et al. 1985, p. 1,056). They derive

    satisfaction from what they are able to contribute to the

    organization. Benevolents are interested in investing in a

    long-term employment relationship with their employer.

    Those falling within the middle range of the continuum are

    called the equity sensitives who prefer their outcomes and

    contributions to be equal (Huseman et al. 1985, p. 1,056).

    Finally, those at the other end of the continuum are the

    entitleds who prefer their outcomes to exceed their

    inputs (Huseman et al. 1985, p. 1,056). These individuals

    are more concerned with what they can gain from their

    organization. Treated as a continuum, equity sensitivity hasbeen found to be positively related with organizational

    commitment (King and Miles 1994; ONeill and Mone

    1998), job satisfaction (King et al. 1993; ONeill and Mone

    1998), organizational citizenship behaviors, and self-

    reported job performance (ONeill and Mone 1998). Based

    on the literature, we predict that equity sensitivity will be

    positively related to affective commitment and civic virtue

    behavior.

    Hypothesis 7 Equity sensitivity will be positively related

    to affective commitment.

    Hypothesis 8 Equity sensitivity will be positively related

    to civic virtue behavior.

    Equity sensitivity may also influence the affective and

    behavioral reactions as a consequence of contract breach

    (Morrison and Robinson 1997). Entitleds are more likely to

    react negatively to contract breach as they are highly

    reactive to situations of under-reward (Huseman et al.

    1987; Miles et al. 1989). For example, King et al. (1993)

    found that entitleds report lower satisfaction when under-

    rewarded as compared to either equity sensitives or be-

    nevolents. In contrast, benevolents are less likely to report

    negative reactions to contract breach as they possess amore liberal threshold for anger (Miles et al. 1989,

    p. 583) and have a greater acceptance of under-reward

    (Miles et al. 1994, p. 586). Benevolents are characterized

    as givers (Huseman et al. 1987, p. 224) and expect little

    reciprocation for their contributions (Miles et al. 1989). For

    example, Miles et al. (1994) found that in identical under-

    reward conditions, benevolents reported significantly

    higher levels of satisfaction than entitleds. Thus, equity

    sensitivity may moderate the relationship between breach

    168 J Bus Psychol (2009) 24:165178

    123

    5/15

    and outcomes such as affective commitment and civic

    virtue behavior.

    Hypothesis 9 Equity sensitivity will moderate the rela-

    tionship between psychological contract breach and

    affective commitment. The effects of breach will be worse

    for low levels of equity sensitivity (entitleds) than for high

    levels of equity sensitivity (benevolents).Hypothesis 10 Equity sensitivity will moderate the

    relationship between psychological contract breach and

    civic virtue behavior. The effects of breach will be worse

    for low levels of equity sensitivity (entitleds) than for high

    levels of equity sensitivity (benevolents).

    Organizational scholars have argued that the experience

    of work is multi-faceted and is influenced by multiple

    factors (Chatman 1989; Davis-Blake and Pfeffer 1989;

    George and Jones 1996; Schneider 1983). Equity sensi-

    tivity has implications for how individuals react to inputs

    and outputs in exchange relationships. In other words,equity sensitivity may have implications for how individ-

    uals react to varying levels of justice. Following the

    interactionist perspective, we predict that the resultant

    interactions involving procedural justice and equity sensi-

    tivity will affect the relationship between contract breach

    and employee outcomes. That is, the effect of procedural

    justice in the relationship between breach and outcomes

    will vary depending upon whether an employee has a be-

    nevolents or entitleds tendency. Assuming that a breach has

    been perceived, if procedural justice is high, there will be

    weaker differences between benevolents and entitleds.

    However, if procedural justice is low, we would expectnegative reactions for both benevolents and entitleds.

    Moreover, since benevolents are more forgiving of trans-

    gressions and accepting of situations of under-reward

    (Miles et al. 1989, 1994), their negative responses toward

    breach would be weaker as compared with the entitleds.

    Entitleds, on the other hand, are likely to exhibit stronger-

    negative reactions toward breach which is accompanied by

    unfair treatment because of their low threshold for situa-

    tions of under-reward (Miles et al. 1989, 1994). That is, a

    combination of an entitleds disposition and low procedural

    justice may lead to the most negative outcomes of breach.

    Thus, we predict the following:

    Hypothesis 11 There will be a three-way interaction

    between psychological contract breach, equity sensitivity,

    and procedural justice on affective commitment. There will

    be a stronger-negative relationship between breach and

    affective commitment for low levels of equity sensitivity

    (entitleds) when procedural justice is low.

    Hypothesis 12 There will be a three-way interaction

    between psychological contract breach, equity sensitivity,

    and procedural justice on civic virtue behavior. There will

    be a stronger-negative relationship between breach and

    civic virtue behavior for low levels of equity sensitivity

    (entitleds) when procedural justice is low.

    Methods

    Participants

    Turnley and Feldman (1999) recommend using diverse

    samples in psychological contract research to allow vari-

    ability in responses. Following this recommendation, this

    study utilized a sample consisting of employees from a

    variety of occupations. Data were collected from two

    groups. The first group consisted of 293 full-time employ-

    ees enrolled in part-time graduate business programs (e.g.,

    business administration, economics, and commerce) at

    three universities in the Philippines. Only those students

    who were currently working full time were included in thestudy. The second group consisted of 110 full-time support

    and administrative staff of a large-educational institution.

    As expected, the MBA sample had lower age, tenure, and

    educational attainment compared to the sample from the

    university sector. There were also significant differences in

    the study variables (e.g., breach, affective commitment,

    equity sensitivity, and procedural justice). These sample

    differences are to be expected. However, in order to

    maintain the diversity of our sample pool and capitalize on

    the statistical power, we combined the two samples in

    analyzing the hypothesized relationships.

    The aggregated sample comprised four hundred andthree employees. About 59% of the participants were

    female while 41% were males. The average age and tenure

    of the participants were 29.4 years (SD = 8.28) and

    5.37 years (SD = 6.13), respectively. A wide variety of

    sectors was represented, including educational and training

    institutions (29%), retail and trade (18.4%), governmental

    agencies (17.3%), manufacturing (11.2%), financial insti-

    tutions (10.2%), service and hospitality (8.2%), information

    technology and telecommunications (4.2%), and consulting

    (1.5%). The jobs held by the participants ranged from low-

    level service positions to middle-supervisory roles. Educa-

    tional background of the participants ranged from thosewith a minimum of a high-school diploma to a PhD degree.

    Procedure

    Survey questionnaires were administered to the participants

    in two stages, approximately 1 week apart. The question-

    naire in stage 1 included the measures of the predictor

    variables while the questionnaire for stage 2 measured

    the moderator and criterion variables. We separated the

    measures of predictor and criterion variables to minimize

    the effects of common method variance (Podsakoff and

    Organ 1986).

    In the first administration of the survey, measures of

    psychological contract breach and demographic charac-

    teristics were included. We received a total of 583 out of

    650 questionnaires distributed (response rate of 89.69%).

    In the following week, a second-survey assessing moder-ator (e.g., equity sensitivity, procedural justice) and

    dependent variables (e.g., affective commitment, civic

    virtue behavior) were administered to the 583 participants.

    Of 583 participants from week one, 430 replied, yielding a

    response rate of 76.16% for the second wave of data col-

    lection. The questionnaires obtained from 27 participants

    were removed because they either failed to provide the

    same-anonymous code during both administrations or

    failed to complete the questionnaires. Thus, a total of 403

    participants who completed both questionnaires comprised

    the final sample.

    After the participants completed the self-report mea-sures, they were requested to pass on a rating scale to their

    immediate supervisor to complete. The rating scale asses-

    sed the extent to which the employee engaged in civic

    virtue behavior. Participants were assured that no one in

    their organization would have access to the completed

    questionnaires. A participant-generated code was used to

    match the supervisor ratings with the self-report question-

    naire. After the supervisors had completed the rating forms,

    they were instructed to detach the cover sheet from the

    rating form (this cover sheet had the name of the employee

    being rated on civic virtue behavior), place it in sealed

    envelope and mail it to the researchers. A total of 137

    (34%) supervisors returned the completed ratings.

    Measures

    Unless otherwise stated, participants responded using a

    seven point likert scale (1 = strong disagree and 7 =

    strongly agree). The coefficient alphas for the variables are

    also reported below.

    Psychological contract breach. This 5-item measure

    was taken from Robinson and Morrison (2000). We

    utilized a global measure as opposed to multiple facets or

    components (e.g., relational vs. transactional) of the psy-

    chological contract because it best captures employees

    perceptions of how well the organization has fulfilled its

    obligations to them (Robinson and Morrison 2000). This

    scale yielded a coefficient alpha of .87.

    Affective commitment. Affective commitment was

    assessed using the 6-item measure designed by Allen and

    Meyer (1990). This scale yielded a coefficient alpha of .81.

    Civic virtue behavior. Civic virtue behavior was asses-

    sed using the 4-item measure designed by Podsakoff et al.

    (1990). Internal consistency reliability of the self-reported

    scale for civic virtue was .74. We also requested supervi-

    sors to provide an assessment of their employees civic

    virtue behavior. The same four items were used. Internal

    consistency estimate was .83.

    Equity sensitivity. The participants equity sensitivity

    orientation was measured using the ESI (Huseman et al.

    1987). This instrument has been found to exhibit highinternal reliability, uni-dimentionality, is consistent with

    the theoretical perspective, it is derived from and is based

    on a non-student sample (Foote and Harmon 2006). The

    only criticism on ESI has been based on its dichotomous

    response pattern (as opposed to a continuous scale) repre-

    senting benevolents and entitleds. Foote and Harmon

    (2006) suggested expanding the response options to include

    benevolents, equity sensitives, and entitleds. However,

    Blakely et al. (2005) found that benevolents and equity

    sensitives reacted similarly in terms of organizational cit-

    izenship behaviors. Therefore, we have chosen to use the

    instrument in its original form of two responses. Thisinstrument consists of a five item forced-choice response

    format. Participants were instructed to allocate a total of

    ten points between two response options for each item. One

    of these options depicts a focus on personal outcomes (the

    entitleds response) while the other presents a way of

    maintaining a long-term employment relationship with the

    organization (the benevolents response). A sample item is,

    My personal philosophy in dealing with the organization

    would be: AIf I dont look out for myself, nobody else

    will, BIts better for me to give than receive. Points

    assigned to the options that refer to the benevolents

    response are added together resulting in participants

    scores ranging from 0 to 50. Higher scores represent a

    benevolents tendency and lower scores represent an

    entitleds tendency. Previous studies have yielded a coeffi-

    cient alpha of .86 (ONeill and Mone 1998) and a test

    retest reliability of .80 (Miles et al. 1989). For this study,

    Cronbachs coefficient alpha was .75. In line with previous

    research, the present study has treated the score derived

    from the Equity Sensitivity Instrument as a continuous

    measure (Kickul and Lester 2001; ONeill and Mone

    1998).

    Procedural justice. Procedural justice was assessed with

    a 6-item measure taken from Niehoff and Moorman (1993).

    It contains items which refer to fair procedures and deci-

    sion making in the workplace. This scale yielded a

    coefficient alpha of .87.

    Control variables. Four-control variables were used in

    the statistical analyses to rule out alternative explanations

    in our findings. Age and tenure were assessed using an

    open-ended response format. A dummy-coded variable was

    used for gender (0 = male and 1 = female). In order to

    control for the effects of context, sample site was also

    included as a control variable (0 = MBA sample and

    1 = university sample).

    Results

    Descriptive statistics, inter-correlations, and internal con-

    sistency reliabilities of the study variables are summarizedin Table 1. As previously noted, internal consistency of the

    scales was acceptable, with alpha values ranging from .74

    to .87. As shown in Table 1, there were significant corre-

    lations between psychological contract breach and outcome

    variables. All were in the expected direction. Overall,

    correlations were generally low to moderate and multi-

    collinearity was not a threat to the stability of the regres-

    sion analyses reported below (Tabachnick and Fidell

    1996). There were also significant correlations between

    some of the demographic characteristics and the study

    variables as depicted in Table 1. Given these relationships,

    we controlled for the effects of demographic variables inall analyses reported below.

    We next conducted a series of hierarchical multiple

    regression analyses to assess the incremental-explanatory

    power of variables in each block and to control statistically

    for demographic variables (Aiken and West 1991). The

    first set of analyses examined affective commitment as the

    dependent variable while the second set of analysis looked

    into civic virtue behavior. To fully test for the two- and

    three-way interaction effects, we followed the guidelines

    suggested by Aiken and West (1991) for moderated

    regression. In particular, we examined the sign and sig-

    nificance of the slope of the relationship between

    psychological contract breach and the focal-moderating

    variable. We plotted the slopes at one standard deviation

    above and below the mean of the focal-moderator variable.

    Analysis with Affective Commitment as the Dependent

    Variable

    Main effects. Table 2 shows the results for the regression

    analysis with affective commitment as the dependent var-

    iable. Psychological contract breach, equity sensitivity, and

    procedural justice explained additional variance above the

    effect of demographic variables on affective commitmentDR2 = .27, F(3,393) = 55.66, p\ .001. Psychological

    contract breach was found to be negatively related to

    affective commitment, (b = -.21, p\ .001), thus sup-

    porting Hypothesis 1. Procedural justice also significantly

    predicted affective commitment (b = .39, p\ .001), sup-

    porting Hypothesis 3. However, the hypothesized

    relationship between equity sensitivity and affective com-

    mitment (b = .05, ns) was not found. Thus, Hypothesis 7

    was not supported.

    Two-way interactions. As can be observed in Table 2,

    our results revealed that the interactive effect between

    breach and equity sensitivity in predicting affectivecommitment was approaching significance, DR2 = .01,

    F(2,391) = 2.99, p\ .054. The breach 9 procedural jus-

    tice interaction term was not found to be significantly

    related to affective commitment, b = -.03, ns. Hypothesis

    5 was not supported. Although the significance level of the

    moderating effects of equity sensitivity does not conform

    to standard statistical conventions, we still plotted the

    slopes at one standard deviation above and below the

    mean of equity sensitivity (which represents high and low

    levels of equity sensitivity) given the counter-intuitive

    results. Higher scores represent benevolents and lower

    scores represent entitleds. The slopes for both high

    (benevolents) and low levels (entitleds) of equity sensi-

    tivity were statistically significant. However, contract

    breach had stronger-negative effects for the benevolents,

    t(190.5) = -4.83, p\ .001 compared to entitleds,

    t(190.5) = -2.4, p\ .05. As can be observed in Fig. 1, at

    low levels of breach, benevolents had a higher degree of

    affective commitment. However, at high levels of breach,

    the degree of affective commitment for benevolents and

    entitleds was almost equivalent. Hypothesis 9 was mar-

    contract breach 9 equity sensitivity interaction was not

    significant at high levels of procedural justice (b = -.08,

    ns). However, the interaction was marginally significant at

    low levels of procedural justice (b = -.13, p\ .06). To aid

    interpretation, this interaction was plotted. As depicted in

    Fig. 2, the slopes for high (benevolents), t(395) = -4.35,

    p\ .001, and low (entitleds), t(395) = -3.99, p\ .001,

    equity sensitivity were statistically significant, but there was

    a stronger-negative relationship between breach and affec-

    tive commitment for the benevolents as compared to the

    entitleds. Hypothesis 11 was partially supported.

    Analysis with Civic Virtue Behavior as the Dependent

    Variable

    Main effects. Table 2 also depicts the results for the

    regression analysis with civic virtue behavior as the

    dependent variable. Psychological contract breach was

    significantly related to self-reported (b = -.11, p\ .05)

    and supervisors assessment of civic virtue behavior

    (b = -18, p\ .05), providing support for Hypothesis 2.

    These findings suggest that the greater the magnitude of

    psychological contract breach, the lower the performance

    of civic virtue behaviors by the employees. Procedural

    justice also significantly predicted self-reported civic virtue

    behavior (b = .16, p\ .001) but not supervisor-rated civic

    virtue behavior (b = -.03, ns) providing partial support for

    Hypothesis 4. Additionally, the relationship between equitysensitivity and self-reported civic virtue behavior (b = .13,

    p\ .01) was also significant providing partial support for

    Hypothesis 8.

    Two-way interactions. As can be gleaned in Table 2,

    entry of the two-way interaction terms (breach 9 proce-

    dural justice and breach 9 equity sensitivity) explained a

    significant amount of additional variance in self-reported

    civic virtue behavior, DR2 = .02, F(2,391) = 5.34,

    p\ .01. Table 2 shows a significant interaction between

    psychological contract breach and procedural justice,

    (b = -.15, p\ .05). Simple slope analysis was performed

    to determine the relationship between psychological con-tract breach and civic virtue behavior at high and low

    levels of procedural justice. The slopes for high,

    t(190.5) = -3.44, p\ .001, and low, t(190.5) = -2.01,

    p\ .05, procedural justice were statistically significant.

    Figure 3 shows that the level of civic virtue behavior was

    higher for those who experienced high levels of procedural

    justice, especially at low levels of breach. However, at high

    levels of breach, the lines converged, indicating similar

    levels of civic virtue behavior. Hypothesis 6 was supported.

    Furthermore, the hypothesized two-way interaction

    between psychological contract breach and equity sensi-

    tivity for self-reported (b = -.03, ns) and supervisors

    assessment (b = .01, ns) of civic virtue behavior was not

    found. Thus, Hypothesis 10 was not supported.

    Three-way interactions. In order to test a 3-way interac-

    tion between psychological contract breach, equity

    sensitivity, and procedural justice in predicting self-reported

    civic virtue behavior, a three-way term was computed. After

    controlling for all 2-way interactions in Step 3, inclusion of

    the 3-way interaction at Step 4 did not add any significant

    amount of variance in the prediction of self-reported civic

    virtue behavior, DR 2 = .00, F(1,390) = 2.07, ns andsupervisors assessment of civic virtue behavior,DR2 = .02,

    F(1,123) = 3.05, ns. Overall, Hypothesis 12 was not

    supported.

    Discussion

    The obtained results generally support our argument that

    psychological contract breach has detrimental conse-

    quences on employee outcomes. Breach was negatively

    related to both affective commitment and civic virtue

    behavior. Indeed, employees feelings of psychologicalcontract breach were also negatively related with their

    supervisors assessment of civic virtue behavior. This

    demonstrates that employees who perceived a contract

    breach were also seen by their supervisors as exhibiting

    less civic virtue behaviors. These findings are consistent

    with previous research that examined the direct conse-

    quences of psychological contract breach not only on a

    wide range of self-reported work attitudes and behaviors

    (Kickul and Lester 2001; Kickul et al. 2002; Restubog and

    Bordia 2006; Robinson and Morrison 1995, 2000) but also

    with independent assessments of work behaviors (e.g.,

    OCB-directed at other individuals and the organization;

    Restubog et al. 2006; Turnley et al. 2003).

    Results suggest a significant interaction between breach

    and procedural justice in predicting self-reported civic

    virtue behavior. We found a stronger-negative relationship

    between breach and civic virtue behavior when procedural

    justice is perceived to be high. There are two possible

    interpretations for these findings. First, procedural justice

    buffers the effects of low levels of breach but not when

    there is a high level of breach. That is, the efficacy of

    procedural justice in mitigating the impact of breach on

    employee outcomes may be contingent upon the extent or

    degree of contract breach experienced. Extent or degree of

    breach is analogous to what Shore and Tetrick (1994)

    referred to as size of discrepancy or the perceived differ-

    ence between what was promised and what was actually

    received. Our results suggest that negative consequences

    that arise from low level of breach (or small discrepancies)

    can be minimized by the presence of procedural justice,

    thus, making its impact less harmful. However, even pro-

    cedural justice cannot safeguard against extreme or high

    levels of breach. This finding is especially interesting when

    compared with previous studies on contract breach and

    procedural justice (e.g., Kickul et al. 2002). These studies

    found that procedural justice mitigated the impact of

    breach on employee attitudes and behaviors regardless of

    the extent of breach. However, the present results indicate

    that there is a boundary condition in the buffering role of

    procedural justice. In other words, procedural justice

    appears to be effective in reducing the negative conse-quences that arise from low levels of breach. However, its

    buffering power seems to weaken as the magnitude of

    psychological contract breach increases.

    Second, this interaction is similar to the interaction

    effects found in previous studies where employees with

    more positive attitudes had a stronger-negative relationship

    with outcome variables (Brockner et al. 1992; George

    2003). For example, Brockner et al. (1992) found that

    individuals with relatively high-prior commitment reacted

    more negatively to unfair treatment than did individuals

    with low-prior commitment. Similarly, George (2003)

    found that the impact of employee externalization (oroutsourcing) on work attitudes of permanent staff was more

    negative for employees who had high-job security than

    those with low-job security. These interaction effects may

    be explained by the expectancy-violation hypothesis which

    posits that, people react more strongly to another partys

    actions that violate their previous expectations of how the

    other party is likely to behave (Brockner et al. 1992, p.

    258). In the context of our research, employees reporting

    high-procedural justice have an expectation that procedural

    justice mechanisms in their organization would safeguard

    them against any form of injustice. Breach of the psycho-

    logical contract is a form of injustice (Morrison and

    Robinson 1997; Rousseau 1995). As a result, this produces

    feelings of anger and resentment because the procedurally

    just system which they expected to protect them failed to

    fulfill its function. These explanations were also in accor-

    dance to a betrayal perspective which was found in

    previous research (Restubog and Bordia 2006).

    Although the interactive effects involving breach and

    equity sensitivity in predicting affective commitment were

    only marginally significant, we believe that the counter-

    intuitive findings require further elaboration. Both entitleds

    and benevolents reacted negatively to breach and there was

    a stronger-negative effect for the benevolents. At low

    levels of breach, benevolents had a higher level of affective

    commitment than entitleds. This concurs with previous

    literature on equity sensitivity (King et al. 1993; Miles

    et al. 1994). Benevolents value the intrinsic dimensions of

    their work such as long-term job security and non-material

    exchange with their organization. For example, King et al.

    (1993) found that benevolents, as compared to entitleds,

    place more emphasis on their work and are inclined to

    emphasize an input-focused ideology (p. 311)that is,

    174 J Bus Psychol (2009) 24:165178

    123

  • 8/2/2019 Jurnal1.Simon

    11/15

    what they can contribute to the organization. This ideology

    buffers the effects of low levels of breach for benevolents.

    However, high levels of breach resulted in a sharp drop in

    the levels of commitment among the benevolents. An

    experience of high breach may be inconsistent to benevo-

    lents assumption of what is expected in a good-

    employment relationship and thus may be viewed as a

    betrayal of trust upon which the employment relationship isbuilt. Moreover, breach may implicitly communicate to the

    benevolents that their employer has undervalued the rela-

    tionship in which they have invested.

    Equity sensitivity, procedural justice, and psychological

    contract breach interacted with one another in predicting

    affective commitment. When procedural justice is low,

    there was a significant negative association between breach

    and affective commitment for benevolents. This finding

    suggests that benevolents showed a reduction in their

    affective commitment as the magnitude of contract breach

    increased. This pattern mirrors the two-way interaction

    above. Benevolents have higher commitment at low levelsof breach but drops to the level of entitleds at high breach.

    Thus, benevolents appear to exhibit adverse reactions when

    their employment relationship is threatened.

    There are two insights that can be derived from the

    study. First, our results suggest that benevolents and en-

    titleds have different reactions to varying levels of breach

    and procedural justice. Previous literature depicted

    benevolents as accepting of under-reward situations (Miles

    et al. 1989, 1994). However, having to experience a high

    level of breach and unfair procedures may be quite dis-

    concerting and too much to endure for the benevolents.

    Thus, failure on the part of the organization to adequately

    fulfill the psychological contract and implement fair pro-

    cedures could severely hurt the benevolents, which in turn

    could affect how they will behave towards their organiza-

    tion. In contrast, entitleds reported similar (low) levels of

    input regardless of the amount of breach experienced.

    Second, the general pattern of results suggests that

    employees with an orientation that is favorable to the

    organization (benevolents or those that perceived high

    levels of procedural justice) were more likely to respond

    negatively to psychological contract breach. Similar find-

    ings alluding to the higher they are, the harder they fall

    have been noted in other research (Brockner et al. 1992,

    p. 241; George 2003).

    A further explanation for the differences in finding in

    this study from those in the existing literature can be due to

    cultural differences in the context. As mentioned in the

    introduction, majority of the studies conducted on psy-

    chological contract breach has been in the western

    countries. The Philippine cultural context exhibits the

    prevalence of collectivism, high-power distance, and

    workplace familism (Hofstede 1997; Restubog and Bordia

    2007). In a cultural context marked by high-workplace

    familism (where employees see the organization as an

    extension of the family), employees may be willing to

    withstand a low-level breach because they perceive the

    organization to be generally nurturing and loyal towards

    them thus being worthy of their loyalty and goodwill.

    However, in case of substantial breach of contract, the

    employees may perceive it as a betrayal from within theirsupport and trusted network, perhaps by one of their own.

    This could lead to a situation where even procedural justice

    or benevolence cannot minimize the negative outcomes

    from high levels of breach.

    Study Limitations and Future Research

    This study had three main limitations. First, data were cross

    sectional in nature. Thus, results cannot indicate causality.

    Future research should utilize a longitudinal design to

    provide a better understanding of the cause and effect

    relationships among the variables. Second, while we haveadopted an interactionist perspective in examining the joint

    effects of a situational and dispositional variable in pre-

    dicting employee outcomes, perceptions of procedural

    justice are purely self-report. We were unable to validate

    the authenticity of employees perceptions of procedural

    justice in their respective organizations. A final limitation

    relates to the effect sizes of the interaction effects. How-

    ever, interaction effects are difficult to detect and 1% of the

    variance should be considered important because most field

    studies in social science research have only accounted for

    13% of the variance (Champoux and Peters 1987).

    Despite these limitations, the current study has several

    strengths. From a methodological standpoint, the ques-

    tionnaires for the predictor and outcome variables were

    administered at two separate occasions minimizing threats

    of common method variance (Podsakoff and Organ 1986).

    Another strength is that we collected employee work

    behaviors from an additional source (e.g., supervisors). The

    reliance on multiple informants such as self and supervisors

    is likely to yield superior measures of civic virtue behavior

    (as they overcome same-source bias) and provide a more

    complete picture of how contract breach influences work

    behavior. Finally, this study utilized a diverse sample of

    employees from a wide range of occupations and business

    sectors enabling greater generalizability of the findings.

    We believe that this research not only extends the liter-

    ature on psychological contracts but also makes several

    contributions to organizational behavior research in gen-

    eral. First, we replicated in the Philippines research findings

    from Western countries suggesting the negative ramifi-

    cations of psychological contract breach on employee

    outcomes. The collection of data in the Philippines adds to

    our understanding of the global workplace and suggests that

    psychological contract breach and its harmful effects do

    exist in a non-western context. Second, we provided pre-

    liminary evidence that a high degree of procedural justice

    may not always buffer the effects of contract breach as

    previously noted in the literature (Kickul et al. 2002). While

    our findings are counter to what we have hypothesized, it

    does provide a new insight suggesting that worse outcomes

    are to be anticipated especially if employees have anexpectation that procedural justice can prevent any form of

    contract breach. Since a stronger-negative relationship was

    found between breach and employee behaviors under con-

    ditions of high procedural justice, clearly more research in

    this area is warranted. Third, we also extended the theo-

    retical characterization of the benevolents. Although

    previous research has portrayed benevolents as more

    accepting of situations of under-reward (Huseman et al.

    1985, 1987), this study has demonstrated that they too have

    their limits or threshold for under-reward situations. That is,

    if the quality of their employment relationship is put at risk,

    benevolents are likely to respond negatively. Fourth andimportantly, the simultaneous consideration of a situational

    (procedural justice) and dispositional (equity sensitivity)

    moderators was a worthwhile pursuit. The adoption of an

    interactionist perspective which recognizes the importance

    of both dispositional and situational variables as joint

    determinants of behavior (Schneider 1983; Terborg 1981)

    provides preliminary evidence that procedural justice and

    equity sensitivity combine to influence reactions to psy-

    chological contract breach.

    There is a growing interest in the nature of psycholog-

    ical contracts in different countries (Rousseau and Schalk

    2000). Future research should examine the consequences of

    psychological contract breach from a cross-cultural per-

    spective. The differences in the way employees in

    individualist and collectivist cultures relate to their orga-

    nization are likely to have implications for the nature of

    psychological contracts and consequences of breach. A

    collectivist culture is described as a society where people

    have a high degree of connectedness to others and strong

    emotional ties with institutions (Hofstede 1997). Further-

    more, the relationship between the employer and the

    employee in collectivist societies is likened to a familial

    relationship where the employer assumes the role of a

    parent, while an employee takes on the role of a child

    (Hofstede 1997; Restubog and Bordia 2006). Thus,

    employees expect to be supported, taken care of and helped

    just as in a parental relationship. In line with this reasoning,

    the impact of psychological contract breach would be more

    pronounced in a collectivist culture compared with an

    individualist culture. That is, failure on the part of the

    organization to fulfill what has been promised may be

    interpreted by collectivists as incompatible to the parental

    role that they accord to the organization.

    Conclusion

    There has been an upsurge of empirical studies on psy-

    chological contracts in the past decade. However, some

    questions remained unanswered especially with respect to

    the role of dispositional and situational variables in mod-

    erating the relationship between breach and employee

    outcomes. The results of this study build on the currentbody of research on psychological contracts by examining

    how the interactive effects of equity sensitivity and pro-

    cedural justice influence employee outcomes. In doing so,

    this research demonstrates that the type and intensity of

    ones reactions to psychological contract breach are influ-

    enced by interactive forces of the individuals disposition

    and the organizational procedures.
