AbstractThis study examines the effect of perceived organisational politics on organisational silence through the mediating role of organisational cynicism. In addition, it tests the effect of perceived support on this relationship. A quantitative (questionnaire survey) design was used to gather data from 346 employees in three public hospitals in Iraq. The structural equation model was used for data analysis. The results demonstrate that all the major hypotheses were accepted, and important role of perceived support in reversing the positive relationship between perceived organisational politics and organisational cynicism was also highlighted. Furthermore, the mediating role was clear in terms of organisational cynicism and the relationship between perceived organisational politics and organisational silence.
