It also examines whether trust culture moderates the effect of PA and R&R on the above behavior.The data was collected from 217 full-time employees of manufacturing and service organizations in India. The results of the moderated multiple regression analysis suggest that fairness of PA and R&R significantly influence OCB and employee engagement. For knowledge sharing behavior only the effect of trust culture is significant. Trust culture also influence OCB and moderates the relationship between R&R and OCB.
