The purpose of this study is to find out the relationship between perceived organizational justice(distributive, procedural, interactional), job satisfaction, organizational commitment, and turnover intention information technology firm. I made the theoretical proposed model to explain these relationships between the constructs, identify the operational definitions and 5 hypotheses(6 sub-hypotheses) was established. The research came to the conclusions as follows: First, perceived justice had the positive effect to the job satisfaction and organizational commitment empirically. Second, I found the relationship between job satisfaction and organizational commitment was positive. Third, job satisfaction had not the positive effect directly, but indirect effect via organizational commitment was identified in turnover intention by empirical test. Finally, perceived organizational justice, job satisfaction, organizational commitment, and turnover intention was significantly related and to decrease the turnover intention, varieties of methods and ways would be developed that raise the perceived organizational justice, job satisfaction, organizational commitment.
