主管與部屬關係交換品質與晉升力評分之 關聯性研究－以挑戰性工作經驗 與組織年資為調節變項

Employees interested in upward mobility often depend on the evaluations by their supervisors. Promotability ratings is the indicator of actual promotion. Promotability ratings are important for individuals' career development and organizations' human resource management practices. Previous research shows that there are many factors can influence promotability ratings, the relationship with leader is one of them. Leader-member exchange have positive effect on promotability ratings. However, this study found that the effect of LMX on promotibility ratings came out mixed result. Thus, the author suspects that the studies have neglected temporal variables(i.e., organizational tenure) and behavior variables(i.e., challenge job experience), thus resulting in findings that are incomplete and potentially misleading. Moreover, little empirical research has addressed the effect of two of variables on promotibility ratings. This study examined the interaction among LMX、organizational tenure and challenge job experience to fill the insufficient literature in this stream. This study collected input from Taiwanese companies from multiple industries, with 144 valid questionnaires were collected. We primarily adopted analysis of hierarchical regression to test the relationship between leader-member exchange quality and promotability ratings. At the same time, organizational tenure and challenging job experiences were also taken into consideration. The main effect explains that LMX and promotability ratings have significant and positive relation.In addition, three-way interaction also indicate organizational tenure and challenging job experiences moderates the relationship between LMX and promotability ratings. Specifically, the subordinate of challenging job experiences is high and organizational tenure is low who can require the highest promotability ratings. Supervisor should give the priority promotional opportunities to the subordinate and provide the chance to develop challenging work experience. Subordinates should dare to undertake the challenging task for career success. This study fundamentally differed from prior research on assumption of organizational tenure and challenging work experience have effect on LMX and promotability ratings and has been verified the existence of the three-dimensional interaction. Additionally,the domestic research rarely discuss the effect of challenging work experiences on promotability ratings, this study provides a sample of oriental society to researchers.
