Understanding multifaceted association of relationships among Work Engagement, Task Performance and Organizational Citizenship behavior (OCBI, OCBO) and moderating influence of gender is crucial for organizations determined to encourage inclusive and dynamic work environments. By reformatory gender-related discrepancies within these realms, Organizations have capacity to advocate for equity, inclusivity and employee welfare thereby cultivating heightened levels of work engagement and organizational accomplishment. In this study we investigate Moderating role of Gender on Work Engagement, Task Performance and Organizational Citizenship behavior in Indian IT Sector. Primary data from 208 Indian IT staff was collected and PLS-SEM was used for analysis. The study found that while gender alone may not wield substantial impact on organizational results, the interplay between gender and work engagement assumes significance in sculpting Organizational Citizenship Behavior.
