Prior studies related to transformational leadership have in many cases focused on identifying correlations with organizational performance, job satisfaction, and organizational commitment. This study examined the relationship between transformational and transactional leadership types as distinguished by Bass (1985) and employees' stress symptoms. In a study centered on 301 financial institution employees, the relevance between leadership types and stress was demonstrated. In particular, when leaders exercised transformational leadership, charismatic characteristics were found to have the most significant negative relationship with employees' stress symptoms. Individualized consideration was also found to contribute to stress reduction; however, it was difficult to confirm statistical significance between intellectual stimulation and stress. Furthermore, when leaders exercised transactional leadership, contingent reward was confirmed to have a negative relationship with stress symptoms, while management-by-exception was confirmed as a variable that significantly increased employees' stress symptoms. Through the results of this study, it was confirmed that employees' stress symptoms can be influenced by the leader's transformational and transactional leadership styles.
