A study was conducted to explore the impact of differences in leadership style on the practice of global leadership and management. Data were collected from 391 senior managers from a global organization and 1,701 of their direct reports, 358 straight-line supervisors, and 266 dotted-line supervisors. ANOVA results indicate that transformational leaders were rated significantly higher on all behaviors by their direct reports than were transactional leaders. Straight-line supervisors rated transformational leaders significantly higher on managing change- and relationship-management behaviors, whereas dotted-line supervisors rated transformational leaders higher on learning orientation. Finally, transformational leaders were significantly more self-aware (greater congruence in self vs. direct reports' average ratings) regarding the practice of these behaviors. implications for future research are discussed.
