The purpose of this study was to find out direct effects of organizational commitment, on organizational dissent and the mediator role of organizational support and organizational trust between organizational commitment and organizational dissent were examined. The study used a correlational research design. Structural equation modelling (SEM) was used to test the proposed integrated model explaining relations among organizational commitment, organizational trust, organizational support, and organizational dissent. The data of the study were collected with a "personal information" form, "Organizational Commitment Scale," "Organizational Trust Scale," "Organizational Support Scale" and "Organizational Dissent Scale." As a result of the research, it was found that moral commitment that sub-dimension of organizational commitment did not have a statistically direct effect on any dissent dimension, but it had significant effect on the articulated dissent with the mediator role of organizational support, trust to management and trust to stakeholder. Alienative commitment had a direct and indirect (with trust to management) effect on the articulated dissent. There was no significant effect of calculative commitment on any variables.
