A large part of many people’s workday consists of interactions with others. Yet job design research has
tended to neglect these network interactions as sources of attitudes and behaviors. Looking back at the
history of job design research, we can trace how interest in social aspects of job design have waned and
waxed. In 1971, Hackman & Lawler published a precursor to the Hackman and Oldham (1975, 1976)
Job Characteristics model. In addition to the core job dimensions of variety, autonomy, task identity,
and feedback, Hackman and Lawler included two social dimensions: dealing with others and friendship
opportunities. Prior to 1971, researchers from the Tavistock Institute endorsed aligning the social and
the technical. Despite considerable research on ‘‘socio-technical systems’’ (Cooper & Foster, 1971;
Herbst, 1962; Trist, Higgin, Murray, & Pollack, 1963), the social dimension of job design was excluded
from what became the dominant job design model. Following Herzberg’s (1966) emphasis on the
motivational nature of the job itself, and debate concerning intrinsic and extrinsic motivation (e.g.,
Deci, 1971), Hackman and Oldham chose to focus exclusively on the individual in relation to his or her
task. They dropped ‘‘dealing with others’’ and ‘‘friendship opportunities’’ and modified task feedback
to only include feedback from doing the job itself (in additional to adding task significance and
modifying variety to focus on a variety of skills).
The Hackman/Oldham model generated a tremendous burst of research, but the social aspects of job
design did not reappear until Salancik and Pfeffer’s (1978) social information processing critique. The
SIP framework generated considerable research as scholars argued over whether job characteristics
were objective or socially constructed. The flurry of research died quickly because the effects of social
cues in the experimental situations typical of SIP research tended to be fleeting (as shown by Kilduff &
Regan, 1988). In many ways, Hackman and Oldham seemed to have closed the book on job design.
However, there is now a resurgence of interest in the social aspects of job design. Specifically,
relational job design approaches recognize that tasks seldom occur in isolation (see Grant & Parker,
forthcoming, for a review). There are many important contributions of this relational turn including the
development of measures of social characteristics of jobs (Morgeson & Humphrey, 2006) and analyses
showing that these social characteristics explain significant amounts of variance in turnover intentions,
organizational commitment, job satisfaction, and subjective performance (Humphrey, Nahrgang, &
Morgeson, 2007). Further, theory and research has extended our understanding of how providing
employees contact with those who benefit from their work strengthens employees’ prosocial

motivations, thereby encouraging higher levels of effort, persistence, and helping behaviors (Grant,
2007; Grant, Campbell, Chen, Cottone, Lapedis, & Lee, 2007). The perspective that we discuss extends
these relational approaches by considering job design in the context of social networks of interaction
across the organization. We examine how tasks and the people who perform them are embedded in
structures of relationships with other tasks and people.
Thus, the network approach differs from prior job design developments in explicitly considering the
organization of work as a network—a workflow network in which tasks move between different people
and different departments. This workflow network, over time, comes to be embedded within additional
networks of communication, advice, and friendship that constitute the informal social structure of the
organization. These informal networks, embedded within and, indeed, influencing the more formal
structures of the division of labor, provide the opportunities and constraints that characterize
organizational life. To the extent that individuals in many organizations are increasingly engaged in
collaborative, knowledge-producing work, then tasks require, in addition to the duties stated in formal
job descriptions, a high degree of social interaction, information gathering, and innovation. The design
of such jobs may be as much an idiosyncratic endeavor on the part of individuals (cf. Miner, 1987)
constructing social network links (wittingly or unwittingly) as the result of blueprints in the HR
department.
Thus, a network approach to job design focuses on how social networks in organizations interrelate
with job design in affecting individual and group attitudes and behaviors. Job design, from a network
perspective, can only be understood in the context of the structure of social relationships within which
individual attitudes and behaviors are embedded and from which individuals derive social utility.
Social Networks
Like other successful research programs, the social network approach is constituted around a set of
generative ideas from which are drawn subordinate theories and hypotheses. These hypotheses alert
researchers to hitherto neglected or unnoticed phenomena (see the discussion of research programs in
Lakatos, 1970). The leading ideas that differentiate social network theory from other approaches
include at least the following four interrelated concepts: the primacy of social connections,
embeddedness in social fields, the social structuring of activity, and the social utility of connections
(Kilduff, Tsai, Hanke, 2006).
Social relations
In emphasizing the primacy of social relations, social networkers examine people in the force field of
influences, rather than exclusively focusing on the attributes of the people. To the extent that focal
individuals are studied, it is their positions in social networks that are the focus rather than their
attributes as ‘‘atomized,’’ isolated actors. A social relationship between two people can enhance many
aspects of how the job is perceived and experienced. As one temporary worker famously described,
even the most apparently monotonous work can become a source of delight and satisfaction in the
presence of amusing others (Roy, 1960). In this account of ‘‘banana time’’ enlivening 10-hour days
devoted to the operation of a relatively simple fabric-stamping machine, the objectively impoverished
work is enriched by the anticipation and enjoyment of routine badinage and game playing. Conversely,

the motivating aspects of enriched jobs can be dampened by negative relationships with co-workers and
supervisors (Labianca & Brass, 2006).
Embeddedness
Closely related to the primacy of social relations is the notion of embeddedness (Granovetter, 1985)
that we define as the extent to which economic transactions are embedded in, and affected by, networks
of interpersonal relationships (see also Uzzi, 1997). Even in efficient markets, evidence suggests that
decisions are affected by relationships such as friendship (Kilduff, 1990). Actors typically show a
preference for interacting with similar others (McPherson, Smith-Lovin, & Cook, 2001). Thus,
workflow exchanges can be considered in light of their embeddedness within social relationships. For
example, the motivating effects of job characteristics tend to be moderated by satisfaction with
co-workers and supervisors (Oldham, 1976). Jobs tend to be experienced holistically—they bathe in
the reflected light of individuals’ social relationships with coworkers.
Structure
Perhaps the most distinctive feature of social network analysis is its focus on the structure of
relationships. A social network is defined as a set of actors and the relations (such as friendship,
communication, and advice) that connect the actors (Kilduff & Tsai, 2003, p.135). Although dyadic
relationships form the building blocks for networks, the idea of a network typically implies more than
two actors and the focus is on the pattern of relations among at least a triad of actors. It is typically
assumed that indirect ties (e.g., friend of a friend) are important. For example, in Granovetter’s (1973)
often-cited research on finding jobs, he argued that job search was embedded in social relations that he
defined as strong or weak ties. Tie strength was a function of time, intimacy, emotional intensity, and
reciprocity. Strong ties are friends and family; weak ties are acquaintances. Granovetter found that the
use of weak ties in job search led to higher paying, more satisfying jobs.
Although the research exemplified the primacy of social relations and the embeddedness of relations,
it was Granovetter’s structural explanation for the ‘‘strength of weak ties’’ that generated research
interest in networks. Focusing on the indirect ties in the network, Granovetter argued that strong ties
tend to be themselves connected (part of the same social circle) and provided the job seeker with
redundant information. Weak ties, on the other hand, tend to not be connected themselves; they
represent ties to disconnected social circles that provide more useful, non-redundant information. Job
seekers who used weak-tie acquaintances ended up with more non-redundant information and better
jobs. Burt (1992) modified this approach by simply focusing on whether ties were themselves
connected or not, referring to a lack of connection as a ‘‘structural hole.’’ Thus, although social network
analysis is not unique in its focus on social relationships, one of its distinctive competences derives
from its focus on the pattern of relationships beyond the dyad: the network.
Social utility
The assumption that social networks have utility is embodied in the concept of social capital, a concept
that has at least two somewhat different meanings (Kilduff & Tsai, 2003, p.135). The social capital of
an individual includes the benefits that accrue to the individual as a result of social network
connections, whereas the social capital of a community consists of ‘‘civic spirit grounded on impartial

application of the laws’’ (Portes, 2000; see also Putnam, 1996). Social capital at the individual level can
be contrasted with human capital: the skills, abilities, and experience that individuals possess as a result
of education and training.
We focus here on the first approach to social capital, which emphasizes the utility of social network
connections. This approach is exemplified by the studies that show that an actor’s position brokering
between others provides information and control benefits to the actor (e.g., Granovetter’s (1973) weak
tie explanation or Burt’s (1992) focus on ‘‘structural holes’’). In contrast, actors embedded within
relatively closed groups may benefit from high levels of trust and may be constrained by high levels of
monitoring (Coleman, 1990). Connecting to the ‘‘disconnected others’’ (across structural holes) can
change the individual’s experience of his or her job in terms of variety, autonomy, feedback, and
significance. But, to the extent that an individual inhabits such an open network, the individual’s
reputation within the organization may suffer either because the individual’s attempts to perform a
brokerage role incurs the sanctions of others (Burt, 1992) or because the individual’s identity is difficult
for others to discern (cf. Podolny, 2001). Individuals within closed networks are likely to experience
lowered autonomy, less variety, and redundant feedback (cf. work on Simmelian ties: Krackhardt &
Kilduff, 2002); but such effects may be outweighed by interpersonal trust and support.
With these four ‘‘leading ideas’’ in mind, we turn to a more detailed analysis of the interrelationships
between social networks and job design. We organize our analysis around the job characteristics (and
resultant job attitudes of satisfaction) and performance.
Job Characteristics
Important features of job design such as autonomy may be subject to relatively invisible social network
constraints. A focus exclusively on the characteristics of a job can miss the ways in which jobs are
embedded in networks of relationships (Brass, 1981). The autonomy of the individual is affected by the
surrounding structure of relationships. A densely connected group of work partners facilitates
the development of trust and the monitoring and enforcement of norms of reciprocity (Coleman, 1990).
We can trust our closely knit group of coworkers because interconnections among them provide for
easy monitoring of norms and sanctions against inappropriate or opportunistic behavior. Thus, the
diamond merchants in New York can exchange thousands of dollars worth of diamonds without the
worry of theft because the diamond community is highly connected (Coleman, 1990).
Although this network structure may provide for smooth operations, it also inhibits the autonomy
of any one individual. Individuals are constrained by the norms and expectations of the dense group of
interactions. Thus, we expect that network density (percentage of ties divided by total number of
possible ties), particularly in the surrounding work group, to be negatively connected to task autonomy.
Feedback concerning job performance—an important aspect of job design—is likely to be richer
and more diverse to the extent that individuals’ work connect them to people or groups who are not
themselves working together. To the extent that the individual is constrained within a closed network of
people whose work connects them to each other, then the individual is likely to receive redundant
information concerning work performance and other aspects of tasks. Likewise, skill variety is likely to
be affected by the extent to which the individual’s personal network (of friends and acquaintances
within the organization) resembles a closed network (e.g., a clique) or an open network of relatively
unconnected people. An open network can provide the individual with a variety of communications that
can foster creative solutions to work-related problems, or lead to innovations in jobs (Burt, 2004). Such
creative activity naturally increases skill variety. Further, task significance may be enhanced by the

extent to which an individual’s personal and workflow network contacts reach out to different parts of
the organization rather than remaining limited to the immediate work group. Relationships with
workers in diverse parts of the organization may provide the individual with a broader, enhanced
perspective on how his/her job affects others in the organization.
Although we expect that strong, direct relationships will have more effect than distant, weak
relationships, we also know people seek out others who have attitudes similar to their own. Similarity
breeds interaction and interaction is the medium of influence and increased similarity as individuals
with similar attitudes reinforce each other and become even more similar. Differences in attitudes of
dissimilar others have little effect: disagreements can be attributed to the dissimilarity, and may even be
used to reinforce one’s own attitudes. Dyadic influence between friends is amplified when we consider
the triadic effects and the larger network. That is, influence attempts of one friend are more likely to be
successful when they are reinforced by several interconnected friends (Krackhardt, 1998).
When similarity centers on attributes such as gender and ethnicity, persistent patterns of structural
divide may form (Brass, 1985; Mehra, Kilduff, Brass, 1998). Homophily may also form around job
functions: engineers preferring to interact with engineers; sales people preferring other sales people.
Such persistent structural divides may provide cohesion to those grouped within clusters, offering
social support and identity confirmation (Milton & Westphal, 2005). Although these patterns may be
dysfunctional for the entire organization, they may enhance perceptions of task significance and task
identity within a particular functional group.
An alternative explanation for attitude and behavioral similarity derives from social comparison
theory (Festinger, 1954). People, in making important decisions or in constructing attitudes in
circumstances in which objective criteria are unavailable, tend to look to similar others (see Oldham,
Kulik, Ambrose, & Stepina, 1986, for an application to job design). From a social network perspective,
there is intense debate concerning which types of people serve as comparison others (see Kilduff and
Oh, 2006, for a review of this debate). A cohesion perspective suggests that people turn to their friends
when seeking advice concerning job-related issues (cf. Kilduff, 1990). In contrast, the structural
equivalence perspective (Burt, 1982) suggests that, in competitive environments, people compare their
attitudes and behaviors against those who occupy equivalent or similar positions in the social network.
Thus, people whose workflow relationships encompass the same others (they receive work from the
same other people and provide work to the same other people) are structurally equivalent and may see
themselves as rivals in the job design arena. They occupy identical jobs in terms of the organization of
work.
Alternatively, it may be that individuals occupying identical positions in social networks are
recipients of the same kinds of information and social pressure, and this leads to similarity of job
attitudes and decisions in the absence of any rivalry—a process known as social cohesion (Friedkin,
1984). Research suggests that both cohesion and structural similarity approaches can explain
similarities in attitudes (see Brass, Galaskiewicz, Greve, & Tsai, 2004 for review). To understand the
outcomes of job design for a set of people requires, however, understanding which other people are seen
as similar in the social network for purposes of social comparison concerning jobs and job-related
outcomes.
Performance
Intuition suggests that large networks may be beneficial to performance. If social capital has
advantages, let us build lots of social capital by connecting to lots of people. And, other things being

equal, large networks are probably more advantageous than small networks. But just making lots of
connections at random is inefficient—your return on time and effort is unlikely to be optimal (Burt,
1992). Rather, connections to a limited set of others with whom you have only weak ties (Granovetter,
1973) may enhance performance. People with whom you have weak ties (relative to those with whom
you have strong ties) are likely to have few ties among themselves and, therefore, are likely to provide
you with diverse non-redundant information (cf. Friedkin, 1980). The important principle that has
emerged from this line of thinking is that, in circumstances in which markets are inefficient, individuals
who broker across the disconnected others may reap benefits, whether they are connected to these
disconnected others by strong ties of friendship or weak ties of acquaintanceship (Burt, 1992).
One of the liveliest topics within the social capital arena concerns these brokers who span across the
gaps in social structure referred to as structural holes (Burt, 1992). Job design has tended to neglect the
informal structuring of work relationships that characterizes brokerage. The brokerage role can
consume much of the individual’s energy to the benefit or detriment of the overall organization (Burt &
Ronchi, 1990). Evidence suggests that to the extent that individuals’ jobs permit them to occupy such
roles within companies (brokering information, influence, and workflow across disconnected people in
their social network) these individuals achieve faster promotions (Brass, 1984; Burt, 1992) and higher
performance (Mehra, Kilduff, Brass, 2001). Connecting to the disconnected others may be a function of
one’s role in the prescribed workflow (Brass, 1981) or individual initiative in developing ties that go
beyond the prescribed workflow and hierarchy (Brass, 1984).
Further, individuals who move into brokerage positions tend to be the chameleon-like high self-
monitors who are able to adapt attitudes and behaviors to the demands of quite different roles (Oh &
Kilduff, 2008). When high self-monitoring individuals reach positions of power in organizations, they
take advantage of the discretion that comes with formal power to flexibly adapt their roles to the
changed requirements of their jobs. For example, in a service-oriented organization, in which upbeat
emotions were an important part of the front-line employees work, emotional help to unhappy
employees was provided by the managers who were high rather than low self-monitors (Toegel, Anand,
& Kilduff, 2007).
Self-monitoring helps explain why some people rather than others tend to be more influenced by
others in forming their job attitudes and decisions (Kilduff, 1992) and why some people rather than
others occupy brokerage roles in organizations (Mehra, Kilduff, & Brass, 2001). As a general
proposition, however, the network perspective suggests that, irrespective of self-monitoring
orientation, how well people do their jobs and how satisfied they are with their career progress
may depend on the extent to which they occupy work roles that allow brokerage across disconnected
others. Returns on social capital investments are likely to be higher in brokerage roles than in other
organizational roles. The extent to which individuals are able to benefit from the trust they have earned
in the execution of their jobs may be contingent on a social network of contacts within which the
individual is embedded, a contingency over which the individual may have exercised little or no
control.
In seeking to extend the ‘‘holeyness’’ and range of their social networks in organizations, people
have to overcome preferences for interacting with others similar on demographic characteristics.
Indeed, within work groups demographic differences tend to be unrelated to the development of
structural holes (Balkundi, Kilduff, Barsness, & Michael, 2007) or restrictions in cognitive diversity
(Kilduff, Anglemar, & Mehra, 2000). However, outside of the intense interactions characteristic of
work groups, default tendencies of social segregation based on gender and ethnicity do tend to appear
(Mehra, Kilduff, & Brass, 1998). Indeed, it is these tendencies, along with proximity, that result in
network clustering (to the advantage of brokers who bridge across clusters). By bridging clusters,
brokers not only acquire non-redundant information but also are first to see synergistic opportunities
(Burt, 1992).

JOB DESIGN: A SOCIAL NETWORK PERSPECTIVE 315
Zooming out from individuals, one encompasses teams, departments, organizations, and, indeed, the
network of inter-organizational relations (Balkundi & Kilduff, 2005; Ibarra, Kilduff, & Tsai, 2005).
Zooming out in this way illustrates the reciprocal embeddedness of job design and networks of
relationships. As patterns of workflow change, so does the structuring of work teams (Kilduff, Funk, &
Mehra, 1997). The performance of teams benefits from a moderate level of disconnectedness. Teams
with neither very few nor very many structural holes tend to outperform fragmented or very cohesive
teams (Balkundi, Kilduff, Barsness, & Michael, 2007). Further, team performance may benefit from a
mixture of internal density among members and external connections to disconnected others (Reagans,
Zuckerman, & McEvely, 2004). Weak ties from one team to another enhance the search for non-
redundant information but strong between-team ties provide the structure necessary for the transfer of
complex information (Hansen, 1999).
These performance implications of social networks may be contingent on the nature of tasks.
Unstructured, relative to highly routinized tasks, may benefit from diverse, non-redundant contacts
(Burt, 2000). But even routine tasks can benefit from non-routine connections that facilitate
performance by bypassing prescribed, bureaucratic workflow procedures.
Conclusion and Future Directions
As the field of organizational behavior moves away from an exclusive focus on individuals to consider
people in organizations in terms of their embeddedness in social networks (e.g., Kilduff & Krackhardt,
2008), this relational turn encompasses that important aspect of organizational behavior involved in job
design. Building on these new directions, we have explored a social network perspective on job design.
Among the ideas we have suggested are these.

Relatively more is known about the practical design of jobs than the design of social networks. It is
difficult for managers to suggest to employees that they change their social networks (especially strong
ties). However, managers can structure formal task assignments in order to expose employees to others
with differing perspectives. Cross-functional teams often serve this purpose as well as committee
assignments and training programs. Informal activities (e.g., organizationally sponsored team sports)
can promote weak ties. Managers can promote enriched social jobs by creating a culture encouraging
differing perspectives and creative problem solving. Job design should include an awareness of the
embeddedness of jobs in social networks of friendship, acquaintanceship, and even kinship (cf. Burt &
Ronchi, 1990) in addition to an isolated focus on the particular task. Simple awareness of the results of
social network research may encourage motivated employees to build ties to dissimilar others. A social
network perspective on job design reveals the embeddedness of work in structures of social ties that
powerfully constrain and enable the initiatives and achievements of individuals.
