This study proposes a conceptual model for examining the formation of perceived job productivity and its antecedents. In the model, leader-member exchange and job satisfaction both directly and indirectly influence perceived job productivity, with the latter effect occurring through the mediation of organizational commitment. Gender moderates each model path. The moderating effects are simultaneously tested using data from 344 engineering staff of a large Taiwanese high-tech manufacturer. Lastly, the empirical findings and their implications are discussed.
