In order to achieve greater efficiency and effectiveness and finally achieve the set goals, organizations must pay enough attention to their human resources and take the most effective step in realizing the goals of the organization by respecting the values and needs of the employees.

The aim of this study was to investigate the effect of organizational justice on organizational commitment with the mediating role of positive organizational behavior of primary school principals. The present study was quantitative in terms of data collection method. The target population of this study was all principals of primary schools in Zahedan that 114 people were selected as a sample by stratified sampling method. Data were collected using three questionnaires of organizational justice, organizational commitment and positive organizational behavior. Content validity was used to determine the validity of research instruments and Cronbach's alpha coefficient was used to determine the reliability, which was estimated to be 0.93, 0.85 and 0.91, respectively. Stepwise regression test and structural equation modeling (SEM) were used for statistical analysis of data.

The results showed that organizational justice has a positive and significant effect on the organizational commitment of primary school principals at 99% confidence level (P <0.01). The results also showed that positive organizational behavior in the relationship between organizational justice and organizational commitment at the 95% confidence level plays a mediating role (P <0.05). The results of stepwise regression test showed that among the components of organizational justice, the component of interactive justice was able to predict organizational commitment and also among the components of positive organizational behavior, the component of self-efficacy is able to predict organizational commitment of primary school principals.

It seems that effective steps can be taken to improve the level of organizational justice in offices and schools by examining structural obstacles such as by-laws and instructions that contradict organizational justice.
