Abstract
Job crafting has become an essential strategy for kindergarten teachers to cope with increasing job demands and sustain professional engagement. Drawing on the proactive motivation model, this study examines whether and how principals' servant leadership exerts cross-level effects on teachers' approach and avoidance job crafting. Data were collected from 1724 teachers nested within 150 kindergartens, and hypotheses were tested using multilevel modeling. The results indicated that principals' servant leadership had significant cross-level effects on teachers' approach and avoidance job crafting, positively predicting approach job crafting and negatively predicting avoidance job crafting. In addition, organizational identification functioned as a cross-level mediator in this relationship, through which servant leadership further enhanced approach job crafting and reduced avoidance job crafting. These findings extend the literature by revealing the motivational pathway linking servant leadership to distinct forms of job crafting and highlight the importance of cultivating a servant leadership climate to foster proactive behaviors among kindergarten teachers.
