Discussion
The present study examined how transformational leadership stimulates employee job crafting via increasing employee adaptability, and how employee identification with the organization influences the effect of transformational leadership. The results showed that transformational leadership had a direct effect on seeking resources; adaptability fully mediated this relationship. The results also supported the conditional indirect effects of transformational leadership on seeking resources and seeking challenges. These findings suggest that transformational leadership seems to be more effective in indirectly fostering expansion job crafting via increasing employee adaptability, especially when employees are less identified with the organization. It appears that transformational leaders encourage employees to enrich their job characteristics by increasing job resources and job challenges (e.g., asking colleagues for advice or learning new working skills). This finding corroborates the study by Piccolo and Colquitt (2006) in which it was found that under transformational leadership, employees tend to experience high levels of skill variety, task identity, task significance, autonomy, and feedback (i.e., core job characteristics, Oldham & Hackman, 2010).
