ABSTRACT

Leadership as an antecedent of the success of an organization remains an interesting topic of study. We focus on a discussion of antecedent variables of transformational and transactional leadership in relation to their effect on work performance among middle-level leaders in the Pelabuhan Indonesia III (Persero) corporation. The variables used in this study are transformational and transactional leadership, organizational commitment, and work performance, and the sample was 30 respondents, which represented 75% of the total population. A questionnaire was used as the data collection technique in this study in order to minimize interpretation differences between respondents and researchers. Partial Least Squares (PLS) regression was selected to analyze the study data as a form of structural equation modeling, to ensure that the results were valid. The middle-leaders as the sample of this study demonstrate good transformational leadership style, and this leadership style does have a significant impact on employees’ organizational commitment. Afterwards, this study also shows that the transactional leadership is better that transformational leadership. The significance of this study is to contribute theoretical ideas, empirically and practically, in the development of human resource knowledge.
