This study aims to examine the mediating effect of job crafting on the relationship between job autonomy and career commitment, as well as the moderating effect sense of calling has on job crafting and career commitment. The data for this three-wave study were collected from 350 R&D engineers at 25 high-tech companies in Guangdong Province, China. The PROCESS macro for SPSS was used to analyze the proposed hypotheses. The results revealed that (a) job crafting mediates the positive relationship between job autonomy and career commitment and (b) sense of calling moderates the indirect effect of job autonomy and career commitment through job crafting, such that the indirect effect is stronger in people with higher sense of calling than those with lower sense of calling. Theoretical and practical implications of the findings are discussed.

This study examines the association between calling and crafting behavior by proposing a moderated mediation model. Drawing from the job crafting perspective and selfdetermination theory (SDT), career commitment is identified as the mediator, and occupational self-efficacy and job autonomy are identified as the moderators in the model, respectively. The authors tested the proposed relationships with an SPSS macro that utilizes a sample of 338 employees in a three-wave procedure. Results support all the hypotheses. The findings reveal calling to be significantly associated with employees' job crafting behavior. Such a process begins with one's career commitment and is strengthened by the level of occupational self-efficacy in the first stage as well as the level of job autonomy in the second stage, thus yielding a pattern of moderated mediation. These findings answer recent calls for an integrative examination of calling in the workplace by demonstrating that career commitment along with occupational self-efficacy and job autonomy represent key mechanisms in transferring one's calling into job crafting behavior. As such, this study complements existing literature on the theoretical and practical implications of calling.
