2.1. Organizational Citizenship Behaviors The concept of Organizational Citizenship Behavior (OCB) was coined by Bateman and Organ (1983) out of a conviction that job satisfaction affected people’s willingness to help other colleagues in varied and mundane forms in order to maintain organized structures that govern work. A number of different dimensions of citizenship behavior have been suggested since its conception nearly two decades ago (Todd, 2003). Torlak and Koc (2007) mentioned the concept of “citizenship behavior” is used for the first time to express supra-role (or extra-role) behaviors whose relations are examined with job satisfaction (Bateman and Organ, 1983). These kinds of behaviors cannot be prescribed or required in advance for a given job (Katz and Kahn, 1966). Supra-role behaviors strengthen social structure of the organization but do not affect the task performance directly.
