Some basic socio-demographic questions were included. The study resulted emotional intelligence was significantly and negatively related to work-family conflict(r=-0.26, p ≤ 0.01) and significantly and positively related to organizational citizenship behavior(r=0.62, p ≤ 0.01). The negative relation between work-family conflict and organizational citizenship behavior was also significant(r=-0.27, p ≤ 0.01).  it was found that work-family conflict is a partial mediator between emotional intelligence and organizational citizenship behavior.
