Exploring alternative relationships between perceived investment in employee development, perceived supervisor support and employee outcomes

The purpose of this study was to explore alternative relationships between perceived investment in employee development (PIED), perceived supervisor support (PSS), and employee outcomes in the form of attitudes (affective commitment and turnover intention) and work performance (work effort, work quality and organisational citizenship behaviour). A cross-sectional survey among 331 employees from a Norwegian telecommunications organisation showed that the relationship between PSS and employee attitudes was partially mediated by PIED. In addition, PSS was found to moderate the relationship between PIED and three self-report measures of work performance. The form of the moderation revealed a positive relationship only for high levels of PSS. These findings suggest that line managers are of vital importance in implementing developmental HR practices, either because they influence how such practices are perceived by employees, which, in turn, affects employee attitudes, or because positive experiences with both line managers and HR practices seem to be needed in order for developmental HR practices to positively influence employee performance.
