This article examines how workplace cynicism moderates the relationship between interactional fairness and perceptions of organizational support (POS). Using a sample of full-time employees, I found a positive, direct effect between interactional fairness and POS. Furthermore, the moderating effect suggests the relation between interactional fairness and POS was stronger for less cynical employees. Incorporating a social exchange framework, this article discusses how the typically positive effect of interactional fairness is lost on cynical employees. This result was confirmed using a controlled scenario-based protocol, which replicated the results of the field study. Practical implications and directions for future research are discussed.
