Deviant behaviors of employees have been into research considerations for long however, research on constructive deviance behaviors, keeping in view its non-contingency, still needs consideration. This study focuses on determining how Person-Organization Fit (P-O fit) predicts Constructive Deviance Behavior (CDB) among employees. To analyze the mechanism involved, Psychological Ownership (PO) is studied as a mediating mechanism between the direct relationship of person-organization fit and constructive deviance behaviors. Moreover, Collectivist Orientation (CO) is taken as a moderating variable on the relationship of psychological ownership and constructive deviance behaviors. A total of 561 managerial employees from informatics industry were included in the sample. Findings show that person-organization fit, psychological ownership and collectivist orientation were significantly related to constructive deviance behaviors. Psychological ownership mediates the link between person origination fit and construct deviance behaviors, while collectivist orientations moderate the relationship between psychological ownership and constructive deviance behaviors. At the low, moderate, and high levels of collectivist orientation (moderator), conditional indirect effects of person-organization fit on constructive deviance behaviors through psychological ownership (mediator) were significant. Future research studies may examine other antecedents (such as building coalition and networking) of constructive deviance behavior through other mediating mechanism (such as psychological empowerment), while the consequences (such as creative performance and innovative performance) of constructive deviance behaviors are also needed to be explored to create awareness about the positive side of deviance behaviors.
