Purpose: The aim of this study was to present a causal model of job motivation with organizational-citizenship behavior (OCB) and the mediating role of organizational commitment in teachers in Ramhormoz, Iran. Methodology: The sample was 250 (125 females and 125 male) teachers, selected by stratified random sampling method, in the academic year of 2016-2017. The study was applied and research method was correlation using structural equations. The measurement tools used were Herzberg Job Motivation Questionnaire (1966), Oregon and Kanovsky (1996) OCB Questionnaire (1996), and Allen and Meyer (1990) Organizational Commitment Questionnaire (OCQ). Coefficients and structural equation modeling were used for data analysis. Findings: The findings in the direct paths of the model indicated positive direct effect of citizenship behavior on different aspects of organizational commitment and job motivation. Moreover, continuous commitment and emotional commitment had a direct effect on job motivation, but normative commitment did not have this effect. In the intermediary path of the model, citizenship-organizational behavior had positive indirect and negative indirect effects on job motivation, respectively through emotional and continuous commitment, but this effect was not significant through normative commitment. Discussion: According to the results of the research fitness of the proposed model increased after eliminating irrelevant paths and adding up new paths, so a good fit analysis was created for the final model.
