This study investigates how employees’ perceptions of work overload might reduce their creative behaviours and how this negative relationship might be buffered by employees’ access to three energy-enhancing resources: their passion for work, their ability to share emotions with colleagues, and their affective commitment to the organization. Data from a manufacturing organization reveal that work overload reduces creative behaviour, but the effect is weaker with higher levels of passion for work, emotion sharing, and organizational commitment. The buffering effects of emotion sharing and organizational commitment are particularly strong when they combine with high levels of passion for work. These findings indicate how organizations marked by adverse work conditions, due to excessive workloads, can mitigate the likelihood that employees avoid creative behaviours.
