Introduction

Organizations’ environment today, is a dynamic and constantly changing environment. Today᾽s organizations are looking for ways to gain competitive advantage and surpass their competitors. Achieve competitive advantage has led human resources within the organization as a strategic competitive factor, more than any organization to be noticed. Today organizations

are looking to attract and retain employees who can best fulfill their duties and roles and contribute to the efficiency of the organization. In this regard, employees who have an appropriate level of Employee Engagement can have a good job performance and help to their efficiency of the organization. According to the report published by Organization Gallup, only a third (33 percent) of US personnel had Employee Engagement in their jobs and two-thirds of them were without Employee Engagement or it was very low (Organization Gallup, 2010). Employee Engagement to a job function and has parallels

concept has been explained in several ways. Kahn was the first person who raised the theory of Employee Engagement for the first time and founded underpinning of this concept (Baltes, Zhdanova & Parker, 2009; Kim, Shin & Swanger, 2009; Shuck & Wollard, 2010) According to Kahn (1990), Engagement, is a degree of physical and emotional violence in a role. In fact it means that how an individual will interact with a job As well as with other employees and colleagues have a close relationship in the workplace (Ferrer, 2005). Employees who have a high level of Engagement, reveals this feature And in doing tasks have much mental and physical Engagement and have a high regard in the work and tasks and make an emotional connection with their jobs. Engagement in applied meaning as psychological characteristics such as: Cognition and emotion and behavior, including the motivational cases are applied Concepts such as job satisfaction and organizational commitment are separate from them (Shuck, Ghosh, Zigarmi & Nimon, 2013). In general, factors and indicators of Engagement significantly is associated with positive aspects of employee behavior and psychological concepts such as organizational citizenship behavior and organizational commitment (Robertson & Cooper, 2010). However there are many agreements on a variety of indicators including Engagement, But still ambiguity in the definition of these variables can be seen and measured. Robinson et al (2004), offered a definition of the structure the following “employees’ positive attitude to the organization and organizational values. A person has Engagement awareness of their profession and always thinks to improve their and other colleagues’ performance.” In general, factors and indicators of Engagement are significantly associated with positive aspects of employee behavior and psychological concepts such as organizational citizenship behavior and organizational commitment (Robertson & Cooper, 2010). Maslach, Schaufeli & Leiter (2001), considered Engagement as opposed to job burnout and the three dimensions of job erosion. According to them job erosion dimensions are: 1 fatigue at work 2-neglect of the physical and psychological needs 3 - feeling of emptiness and futility. So the low scores on the three dimensions of job erosion can specify a

with the Structures such as job engagement, intrinsic motivation and job satisfaction (Rich, Lepin & Crawford, 2010). Employees who have a high level of engagement - are more subjective, high individual creativity and initiative in their jobs as a result, higher promoting innovation in the entire organization (Hakanen, Perhoniemi & Toppinen-Tanner 2008). Research by Morgan (2004) on 50,000 employees in 59 global organizations to recognize and identify the most effective stimulus on Employee Engagement and to identify best practices in the field, showed that stimulus Engagement affect on creation of emotional and rational commitment and this commitment of also affects on employees’ job performance. Morgan was able to show that increased Employee Engagement can lead to improved 20% of performance and reduce 87% of employees’ desertion. Job performance has been and is an important issue in organizations and industries and due to the importance of the definition of performance should be usable and useful for all strategies and organizational interventions. Job performance includes both vital and important results and behaviors in which contributes in the process of achieving results. Job performance is defined as organizational values and behaviors of employees in different positions and times. Purpose of the organizational value, is estimation that the organization have done from activities and services to its employees, Such as job function or a good working relationship with other employees (Borman et al., 2003). Performance as expected overall values of the organization has defined separate pieces of behavior that a person does during a specified period of time (Motowidlo, 2003). Borman &Motowidlo (1993) divided Job performance into two dimensions, namely: Task performance and performance. The content of the task performance varies in different job situations, While the content of Contextual performance in different situations are similar and it can be predicted on the basis of personality.

and in the last two decades has been provided many different definitions in this regard and this

three-dimensional, three features of Engagement. These three characteristics are: 1. Energy at work 2. Enthusiasm and desire to work 3- the effectiveness in work (Maslach et al., 2001). So employees, who have high Engagement, can establish a positive relationship with job-related activities and high enthusiasm and passion in their duties and somehow can control the needs and demands of the job (Gonzalez, Schaufeli, Baker & Lloret, 2006).

Job PerformanceJob performance has always been an

important issue in organizations and industries. Because of this importance the definition of performance is presented, it should be useable and useful for all strategies and organizational interventions. Researchers have offered various definitions of job performance. Rogelberg (2007), has defined the performance of activities that are normally part of the job and the individual activities and must do it. Performance can be considered as expected overall value of organization from the individual behavior pieces is defined which a person offers over a specified period of time (Motowidlo, 2003). Campbell (1990) also, has defined job performance as person᾽s under the control behavior that affect the organization᾽s goals (Zheng., Kan,, Wen & Dan, 2008).

Task PerformanceTask performance is defined as skill by which

the person performs activities that he is officially responsible for doing them and distinguish a job from other jobs (Christian, Garza & Slaughter, 2011). Task performance includes different behaviors. One type of behaviors includes activities that directly converts raw materials into products and services, Such as selling goods in retail, launching devices in a workshop, teaching in schools or perform a surgery in a hospital (Zheng et al., 2008). Task performance applies to those activities that the technical expertise related to the job, and recognized as part of the job (Chien, Lawler & Uen, 2010).

Contextual PerformanceThe second part of the performance is

Contextual Performance and includes activities

that the person do in order to support social environment of the organization and includes behaviors through impact on psychological and social context, on effectiveness of the organization is effective (Cichy, Cha & Kim, 2009). This type of behaviors is not exclusive to a particular job but it is considered an integral part of every job. The Contextual performance has the potential to be a key structure. Although the task performance has traditionally attracted more attention than Contextual performance but researchers have proven that the Contextual Performance causes competitive advantage of the organization and support organizational objectives and thereby contribute in the overall performance (Witt, Kacmar, Carlson & Zivnuska, 2002).

Research HistoryWagner and Harter (2006), found in

the research that employees with higher Engagement, as much as 12 to 34 percent, will bring greater customer satisfaction and on average 80 thousand to 120 thousand dollars per month will increase sales. So there is closely relationship between Engagement and job performance. In addition, employees who do not communicate with their job, and they have poor performance, it causes that others not do their tasks as deserve, in other words, these people also cause poor performance from co-workers (Dahlqvist & Matsson, 2013). Gorgievski, Baker and Schaufeli (2010), conducted a study on 1,900 employees of the Netherlands. The questionnaire related to the study had been placed for a year and a half on the website of Psychology journal in the Netherlands and visitors were asked to complete questions about Engagement and job performance. In this study job performance was divided into two dimensions. One part of the questions related to job performance structures determining the task performance and the other determining the contextual performance. Data were analyzed using structural equation modeling and analysis results showed that employee Engagement had positive effects on the task performance This hypothesis was significant in less than 0.001 and it was equal to the amount (β = 0.39). Also on this research positive relationship between

Engagement on contextual performance at the level of less than 0.001 became known significant and its amount was determined equal to (β = 0.24).

for each of the questionnaire are presented separately in Table 1. Convergent validity was used to check the validity.

FindingsAccording to the results obtained from the

PLS algorithm Cronbach᾽s alpha values of all Objective variables are shown in Table 1, are Greater than 0.7 the result of model reliability is approved. The minimum amount of the average variance extracted (AVE) equal to 5.0 confirms the existence of convergent validity (Fornell & Larker, 1981). The results in Table 1 confirm the convergent validity of the model. Since the values AVE column or the average variance extracted in Table 1 is larger than 0.5 This means that any structure cover more than needed of its distribution. The results that were obtained through the algorithm automatic driver in the software and can also be seen in Table 2, and the beta values statistically significant for each of the hypothesis of the study is shown. So hypothesis 1 with values (β = 0.811) and (t = 11.76) at the level of p <0.001 is approved. As a result employees Engagement impact

positively and significantly on job performance. Hypothesis 2 with values (β = 0.192) and (t = 6.28) at the level of p <0.001 is approved. As a result, contextual performance has a positive and significant impact on engagement. Hypothesis 3 with values (β = 0.228) and (t = 7.84) at the level of p <0.001 is approved; So engagement has a significant and positive impact on task performance. The final results of the analysis are shown in Figure 2.

Conclusions

The results show a positive impact of engagement on job performance and also contextual performance and employee task performance, These results are parallel with results of Gorgievski et al.(2010) study, As well as engagement does not mean engaging managers in the process of engaging the emotions and minds of the staffs, but it means creating conditions under which employees are more associated with do their work and their duties more enthusiastically recommended: In order to increase the level of enthusiasm and career
