공공부문에서 관계 및 변화지향 리더십행동과 조직변화몰입의 관계: 리더 도덕성의 조절효과와 LMX의 매개효과를 중심으로

The purpose of this study is to shed light on an understudied topic in public sector(ex: Korea Post), namely, commitment to organizational change. This article hypothesizes the direct effects of leadership behavior(change-oriented, relations-oriented) on LMX and change commitment. Also we predict that leadership behavior fosters change commitment among subordinates through the mediating mechanism of LMX, and that leader integrity moderates the relationship between LMX and change commitment. A total of 643 employees of the Korea Post completed a survey on commitment to organizational change, LMX, leader integrity, leadership behavior, and demographic characteristics. The multiple regression analysis were employed to test the hypotheses. The main finding of this study was as follows: First, a leader' relations-oriented behavior had a positive impact on LMX. But a change-oriented leadership behavior was not significantly related to the LMX. Second, a leader' relations-oriented behavior had a positive impact on a change commitment. But a change-oriented leadership behavior was not significantly related to the change commitment. Third, LMX was associated with change commitment. Fourth, the mediating effects of LMX in the relationship between leadership behavior and change commitment was not statistically significant. Finally, the positive relationships between LMX and change commitment were stronger when leader integrity was high rather than low. In particular, this review concludes with implications for future research, limitations of this study, and practical application.
