The aim of this study is to determine the effect of perceived organizational justice and organizational trust on organizational commitment. The sample of the study in the survey model is composed of 566 primary school teachers working in the province and the districts of Edirne during the 2010-2011 educational year. The data of the study was collected using three different scales administered simultaneously. In the study, two basic results were obtained through using Beugre’s ‚Organizational Justice Scale‛, Nyhan and Marlowe’s (1997) ‚Organizational Trust Scale‛ and Meyer and Allen’s (2004) ‚Organizational Commitment Scale‛. First, it was determined that there was a positive and high relationship between the predictive variables of organizational justice and organizational trust and the predicted variable of organizational commitment. Second, the feeling of organizational trust was determined statistically to have higher accountability for the organizational commitment when compared to the feeling of organizational justice. As a result of the Path analysis, it was observed that the sub-dimensions of the organizational trust and organizational justice behaviors predicted the organizational commitment behavior in the positive direction. In conclusion, it can be stated that employees’ high organizational trust and organizational justice perceptions will result in an increased organizational commitment
