This research investigates the impact of transformational leadership (TL) on innovative work behavior (IWB) through the mediating role of organizational resilience (OR) within the Egyptian banking sector. A survey approach was adopted by distributing a standardized instrument to 318 employees in public and private banking branches across Greater Cairo, Egypt, with the data analyzed using structural equation modeling (SEM). The findings suggest that the TL approach adopted by managers significantly promotes employees' IWB. Organizational resilience was identified as a partial mediator in the relationship between TL and employees' IWB. Furthermore, our analysis indicated a positive correlation between the TL approach and OR, which positively contributes to employees' IWB. This study is the first to explore OR as a mediator relating TL to IWB within the Egyptian banking sector. The practical implications of this study indicate the capacity possessed by transformational leaders to improve their employees' innovative behaviors by bolstering OR among them.
