리더의 동기부여 언어가 자아존중감, 자기효능감, 그리고 조직몰입에 미치는 영향

In order to respond quickly to the rapid environmental changes, an organization requires a new way of leadership to enhance organizational members’ motivation and commitment to their organizations. One of the most effective ways to motivate organizational members would be through leader’s language. Although there are many studies identifying what types of leadership are most effective on certain circumstances, there is few studies related to the role of leader’s language to motivate employees. Therefore, this study attempted to identify the impact of leader’s motivational language on employee’s self-esteem, self-efficacy and organizational commitment empirically with 377 Korean Tax officials from National Tax Service (NTS). The results of the study indicated that the leader’s motivational language positively affected on self-esteem, self-efficacy, and three different components of organizational commitment: affective, continuous and normative commitment, indicating the importance of leader’s motivational language. However, the mediating relationships of self-esteem between the leader’s motivational language and three components of organizational commitment were not valid on continuous and normative commitment, whereas, the mediating relationships of self-efficacy were not on continuous commitment and had a very weak impact on normative commitment. These results could carefully indicate that Korean Tax officials from NTS seem to be bureaucratic and inert to show organizational commitment by self-issues, but more depending on the leader’s language to gain more favor with their supervisors. Although this study could not identify the mediating roles of self-esteem and self-efficacy on the leader’s motivational language and organizational commitment, these results were only limited to Korean Tax officials from NTS. Further researches relating on the leader’s motivational language are required to resolve the unknown phenomenon in different types of organizations.
