Abstract: Based on transactional stress theory, this study establishes a moderated mediation model to examine how employees' active coping influences job crafting under family financial pressure and the role of family supportive supervisor behavior in this context. Analysis of multi-time follow-up data from 311 employees reveals that family financial pressure encourages job crafting, mediated by active coping. Enhanced family support intensifies this effect, making active coping more significant. Conversely, in its absence, the effect is negligible. In practice, managers should encourage active coping among employees facing family financial pressures, thereby fostering greater workplace engagement.
