The purpose of this paper is to examine whether different supervisory styles are relevant in facilitating or inhibiting job crafting, and whether job crafting plays a significant role in promoting self-competence and work performance. Data were gathered from 162 employees in a large manufacturing company. We found a positive relationship between promotive control and job crafting, and a negative relationship between restrictive control and job crafting. Some job crafting behaviors positively affect both self-competence and performance, while others have a negative effect. Our results suggest that organizations interested in promoting job crafting should encourage a promotive style of leadership.
