Abstract:

Organizational citizenship behavior (OCB) has been an important and growing area of research for past two decades. Numerous empirical research have identified consequences and antecedents of this extra‐role behavior. This study intends to analyze the influences of job characteristics, job satisfaction, and organizational commitment on OCB. Therefore, a comprehensive model that includes job characteristics, job satisfaction, affective commitment, normative commitment, and OCB at the same is constructed. The model employed by the current thesis proposes that job characteristics affect OCB through the mediations of job satisfaction, affective commitment, and normative commitment. In order to test the hypotheses regarding the relationship between the variables depicted, data was collected from knowledge workers, who do not work manually and perform well guarded skills that others outside the work do not have. The sample used in this study is composed of 225 knowledge workers from four different industries, such as Defense, ITv Telecommunication, Software, and Banking. Data was collected through paper-pen based questionnaires and web based questionnaires. The results of the current study indicated that while job satisfaction and affective commitment fully mediate the relationship between job characteristics and OCB, normative commitment partially mediates this relationship. This study is concluded with discussion of the results, implications for managers and human resource professionals, and directions for future research.
