In an era where home and work domains have become inseparable, it is surprising to see that extant research has placed less emphasis on examining the boundary conditions and mechanisms to understand the home-to-work crossover and spillover process. Building on the work-home resources theory and the crossover-spillover perspective, we test a resource-based crossover-spillover model of how the work-family spousal support provision by one partner relates to the other partner’s creativity at work. We propose that “phubbing” at home, which refers to the behavior which an individual focuses too much on their smartphone and snubs others at home, affects the crossover process of resource exchange between partners. Regarding the spillover from home to work, we propose that job crafting mediate the association between work-family spousal support and employee creativity. Daily diary data were collected from 65 dual-earner couples, over 15 working days in the USA. Results from the multilevel actor–partner interdependence model, which considers the nonindependence of dyadic data, showed that work-family support receipt enhances employee creativity by prompting the employee’s relational job crafting and cognitive job crafting at work. Moreover, our results revealed that the high level of phubbing at home weakens the work-family support crossover between partners. We contribute to the literature by adding evidence regarding the mechanisms that enable social support at home to turn into employee creativity at work.
