Organizations will to own employees doing extra-role behaviors voluntarily in order to improve organizational performance. OB researchers are trying for more than 20 years to identify predictors of these kinds of behaviors, which are called organizational citizenship behaviors (OCBs). One of these predictors is organizational politics perceptions. Although-based on some research results-there is a meaningful negative relationship between organizational politics perceptions and OCBs, workplace spirituality’s potential to reduce negative outcomes of organizational politics perceptions, from one hand, and it’s capability to enhance OCBs, on the other, lead us to study the moderating role of this variable in the relationship between OPPs and OCBs. Hence, this paper is aimed to examine the mediating role of workplace spirituality in relationship between organizational politics perceptions and citizenship behaviors. The results uncovered that the workplace spirituality meaningfully moderates OPPs-OCBs negative relationship.
