This document discusses organizational citizenship behavior (OCB), which refers to individual behaviors in a workplace that are beneficial but not formally rewarded. The authors aim to analyze how OCB impacts various organizational performance measures based on its antecedents and consequences. OCB is described as having two dimensions - behaviors directed at individuals, and behaviors that benefit the overall organization. Various antecedents of OCB are identified, like role clarity, leadership, commitment, and justice. These antecedents are then correlated with five organizational performance outcomes: reduced turnover and absenteeism, employee satisfaction and loyalty, and customer satisfaction and loyalty. The authors argue more research is needed on how demographics like age, gender and experience influence OCB.
