This research study examines the relationship between transformational, transactional and passive/avoidant leadership styles and three dimensions of organizational commitment – affective, continuance, and normative in two subsidiaries of one multinational organization. The research findings revealed that transformational leadership has the strongest impact on affective commitment, although transactional leadership also affects affective commitment. Transformational leadership also has a significant positive affect on normative commitment. Transactional leadership has a significant positive affect on continuance commitment and positive/avoidant leadership has a significant negative affect on affective commitment.
