This study focuses on exploring the intermediary function of teamwork (TW) within the context of higher education institutions and its effect on administrative organizational citizenship behaviors (OCB). Employing a survey methodology, quantitative data were gathered from individuals working in the higher education sector. Data analysis was conducted using partial least squares structural equation modeling. The results affirmed the anticipated intermediary effect of TW in enhancing OCB through the interaction of employee engagement (EE) and organizational learning (OL). Contrary to expectations, direct links between organizational learning and OCB were not substantiated; however, an indirect relationship was identified through TW's mediating role. Additionally, the model accounted for 57.8% of the variance observed in OCB. This research contributes to the body of knowledge on OCB by proposing a new and theoretically grounded mediator, offering insights into how EE and OL at higher education institutions influence OCB via TW.
