Abstract 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. ‎
