Does work passion benefit or hinder employee’s career commitment? The mediating role of work–family interface and the moderating role of autonomy support

Based on the dualistic model of passion, this study explored the relationship between distinct types of work passion and career commitment, as well as the mediating role of work–family interface and the moderating role of autonomy support. A two-wave study was conducted among South Korean workers (N = 250) over a 5-month time period. Results showed that harmonious work passion was positively associated with career commitment, whereas obsessive work passion was not significantly associated with career commitment. Moreover, work–family enrichment partially mediated the positive effect of harmonious work passion on career commitment, and work–family conflict fully mediated the negative effect of obsessive work passion on career commitment. Results further indicated that autonomy support strengthens the positive effect of harmonious work passion on work–family enrichment. Furthermore, this study expanded the understanding of the underlying psychological mechanisms of effects of work passion. The implications and limitations of the study and potential topics for future research are discussed.
