The Impact of Career Growth on Knowledge-Based Employee Engagement: The Mediating Role of Affective Commitment and the Moderating Role of Perceived Organizational Support.

Based on social exchange theory and attribution theory, this paper explores the role of affective commitment and organizational support in the relationship between career growth and the engagement of knowledge workers. The results show that (1) career growth has a positive impact on knowledge workers' organizational engagement; (2) career goal progress and professional ability development promote job engagement; (3) career growth has a positive effect on affective commitment, which in turn influences employee engagement; (4) affective commitment plays a mediating role in the effect of career growth on engagement; and (5) perceived organizational support positively moderates the relationship between career growth and affective commitment.
