This study concerned organizational citizenship behavior(OCB) at public and private research institutes in Korea. Previous studies viewed there is a clear enough conceptual boundary between OCB, or extra-role behavior, and in-role behavior, and presented that justice perception, leadership behavior, job characteristic and personality are important predictors. This study argues the argument that this boundary varies across employees, as employees differed in what they defined as in-role and extra-role behavior.
Using self-reported data from researchers in public and private research institutes, this study examines that the boundary between in-role and extra-role behavior is not clearly defined and that OCB is a function of how broadly employees define their job responsibilities. This study also examines the influence of the justice perception, leadership behavior, job characteristic and personality on role perception that is defining so-called OCB as in-role behavior and that the influence of the duration of interaction of employee’s with his or her supervisor on the similarity of role perception.
This study found that the boundary between in-role and extra-role behavior is not clearly defined and that OCB is a function of role perception. This study found that leadership behavior, job characteristic and personality have relations with role perception and justice perception, leadership behavior, and job characteristic also have relations with OCB, but there is no mediating effect of role perception. This study also found that the duration of interaction of employee with his or her supervisor has an influence on the similarity of role perception.
