Drawing from the conservation of resources theory, this study explored the interplay between role overload and work-life crafting behaviours, emphasising the moderating effects of job demands-abilities fit and Leader-Member Exchange (LMX). Utilising structural equation modelling, data from 342 full-time female primary school teachers in Iran was analysed. Results showed that teachers with a lack of work-life balance crafting behaviours reported heightened job demands. Furthermore, the presence of role overload diminished teachers\\\' tendencies for work-life balance crafting behaviours. Both individual (perceived job abilities-demands) and situational (quality of leader-member exchanges) factors exhibited combined moderation effects on the relationship between role overload and work-life crafting behaviours among these teachers. This research enriches the literature on work-life crafting behaviours, shedding light on the intricate dynamics of work-life balance crafting behaviours influenced by a blend of individual and situational factors.
