A literature review revealed that the effect of organizational justice on organizational citizenship behavior (OCB) had been heavily examined as an overall relationship. However, there is a lack of research that examined the effect of organizational justice dimensions on OCB via affective organizational commitment as a mediator. Therefore, this research is an attempt to provide a value theoretical model that explains the relationships between dimensions of organizational justice and OCB as well as tries to describe in detail meaning of this relationship through the mediating effect of affective organizational commitment in the context of social exchange theory. Furthermore, the proposed hypotheses on the link between these variables are provided as a foundation for further research.
