Should the human resource managers be concerned about cynicism and should they attempt to respond to it or not, depends mostly on whether cynicism has any negative effects on employees or their organizations. Many researchers have found that there is a relation between organizational cynicism and many variables such as job satisfaction, organizational commitment, organizational alienation, and organizational citizenship behavior. As many studies have shown, Cynicism has been associated with negative consequences respecting the employees. Employees that are cynical about their organization, experience a variety of negative emotions, including distress, disgust and even shame when they think of their organizations. These negative emotions result in emotional fatigue and depression. In this study it is attempted to investigate the causes and consequences of organizational cynicism in the Parsian Electronic Commerce Company. For the testing of research hypotheses, structural equation model (SEM) was used. The test results indicated that psychological contract violation, organizational justice, and perceived organizational support, affect the employee’s organizational cynicism; also that organizational cynicism has aneffect on employee’s organizational commitment, organizational citizenship behavior, and their counterproductive work behavior.
