Based on the literature analysis this study proposes that satisfaction mediate the effect of job involvement, intrinsic motivation and procedural justice on commitment in a multinational IT company. Our thesis is based on a theoretical model including seven hypotheses. To further test our model we used two models. In first model we proposed positive effect of job involvement, intrinsic motivation and procedural justice on commitment. In the second model, we proposed mediation of satisfaction on relationship between job involvement, intrinsic motivation and procedural justice and commitment. Proposed theoretical models are tested using questionnaire where employees of the IT Company were asked 30 question relevant to concepts of job involvement, intrinsic motivation, procedural justice, work satisfaction and commitment. Answers were analyzed using multiple regression analysis. We found out that the job involvement, procedural justice and work satisfaction have significant positive effect on commitment. The intrinsic motivation had negative effect on commitment in the first model and insignificant effect on commitment in the second model. We also found out that satisfaction mediates the effect of job involvement and procedural justice on commitment. The implication of the study is thus that managers who want to increase commitment in their organizations should consider having satisfied employees by assuring just procedures.
