Cynicism has begun to become an increasingly important and studied subject in behavioral sciences. Problems and troubles that occur within the organization can cause negative emotions and thoughts to emerge in employees. The concept of cynicism is also one of the leading events of these negative feelings and thoughts. In this study, it was tried to investigate the dimension of the level of cynicism felt by the workers and their influence on the performance of the employees. Questionnaires were applied to the participants in order to collect information in the direction of the study objectives. In this study, Brandes et al. (1999), "Organizational Cynicism Scale" which has been finalized by making some changes by Bozkurt (2015) and "Work Performance Scale" which has been developed by Kirkman and Rosen (1999) and has been changed by Akay (2017) are used. The determined scales were applied to the academic staff of Mardin Artuklu University and the level and dimensions of organizational cynicism of the personnel were tried to be determined and the effect on the employee performance was investigated. As a result of the analysis made, it was found that there is no significant relationship between the cognitive dimension, behavioural dimension of organizational cynicism and the performance of the employee. But there is a significant relationship between emotional dimension of organizational cynicism and employee performance.
