Abstract:Aiming at abusive supervision prevalent in stress, and based on the latest development of job crafting, this paper studies the internal mechanism and boundary of abusive supervision inhibiting or motivating employees' job crafting. Based on regulatory focus and conservation of resource theory, Online questionnaire was adopted, 331 sample data of employees of high-tech enterprises are collected at three time points, and hierarchical regression and bootstrap analysis are carried out. The results show that R&D abusive supervision has an inverted U-shaped effect on promotion job crafting, and has a positive linear effect on prevention job crafting. Situational promotion focus partially mediates the inverted U-shaped impact of abusive supervision on promotion job crafting, while Situational prevention focus fully mediates the positive impact of abusive supervision on prevention job crafting. Core self-evaluation (CSE) moderates the effect of R&D abusive supervision on promotion and prevention job crafting, meanwhile it moderates the mediating role of situational regulatory focus between them. According to the research conclusions, it is suggested that the degree of abusive supervision should be controlled in the level of challenge, and different adjustments should be made to the R&D personnel with different CSE, so as to give full play to their stimulating role.
