Job design in blue- and white-collar jobs: the influence of transformational leadership on job crafting and i-deals

Purpose Whereas job crafting and idiosyncratic deals (i-deals) have primarily been studied in white-collar jobs, there is a lack of research on job design in less skilled and highly structured work. Our study addresses this gap by analyzing the effects of transformational leadership on job crafting and i-deals in blue- and white-collar jobs. Design/methodology/approach To test our hypotheses, we surveyed 285 employees (31.9% blue-collar employees and 68.1% white-collar employees) in the German craft industry, using structural equation modeling for data analysis. Findings Our results show that transformational leadership is a strong predictor of job crafting and i-deals but that its influence depends on the occupational group. More specifically, the moderating role of the occupational group in the relationship between transformational leadership and job crafting differs regarding job crafting’s dimensions. Concerning i-deals, transformational leadership’s influence on both development and task i-deals is stronger in white-collar jobs than it is in blue-collar jobs. Practical implications The study provides new insights into the important role of the work context in which leadership takes place. In particular, these insights can guide leaders in how to manage different occupational groups to engage them in proactive behaviors. Originality/value This study is the first to compare the contextual roles of blue- and white-collar jobs with regard to job design. By examining the influence of transformational leadership on job crafting and i-deals in two occupational groups, our study contributes to research on the role of work context in the effectiveness of transformational leadership in encouraging employees to engage in proactive behaviors.
