Creativity has its ‘dark side.’ This study investigated the relationship between employee creativity and work-family conflict drawing on boundary theory. Data were collected from 1074 participants who were full-time employees. By employing PROCESS macro, we found the relationship between employee creativity and work-family conflict is fully mediated by psychological detachment difficulty. We also found that family-work conflict moderates the effect of creativity on psychological detachment difficulty
such that for those who experience lower family-work conflict, the effect of creativity on the mediator (i.e. psychological detachment difficulty) is stronger than for those who experience higher family-work conflict.
