The aim of this research was to explore the relations among supervisors’ transformational leadership, transactional leadership, and subordinates’ work outcomes (including job satisfaction, organizational commitment, organizational citizenship behavior, and job performance). Using structured questionnaires, a diverse sample of 784 full-time employees drawn from a variety of organizations in Taiwan and mainland China was surveyed. Analyses revealed that transformational leadership was positively related to all four outcome variables in our study; whereas transactional leadership was positively related to job satisfaction and organizational commitment. More importantly, we found that the social-oriented self view enhanced the positive effect of transformational leadership on job performance but mitigated the positive effect of transformational leadership on job satisfaction. On the other hand, the individual-oriented self view mitigated the positive effect of transactional leadership on organizational citizen behavior. It is thus recommended that employee’s self views may be important contingent factors of leadership effectiveness.
