The study selects 142 people from 255 regular employees who work for the university and distributes the questionnaire designed in Likert scale. Cronbach alphas have been determined for organizational citizenship, organizational justice and commitment as 0.924, 0.94 and 0.73, which are well above the minimum acceptable level. The results indicate that procedural justice has the most effect on organizational commitment followed by interactive justice and distributive justice. In addition, obedience has the most influential effect followed by loyalty, partnership, innovation and behavior. Finally, the survey shows that organizational citizenship is influenced mostly by loyalty and partnership. In summary, the effect of organizational justice on organizational citizenship and organizational commitment has been confirmed.
