In the present day, organizations constantly strive for achieving excellence by
enhancing employees’ efficiency and effectiveness. One such way, organization can
achieve this objective is through behavior of the individuals. Individual behavior may be classified into in-role behaviors and extra-role behaviors or Organizational Citizenship Behavior (OCB). Several researchers have found that OCB resulted in organizational effectiveness, efficiency and group performance (Podsakoff et al., 1997; and Podsakoff et al., 2000) and unit performance (Podsakoff and Mackenzie, 1994). Other consequences of OCB include higher salary and promotion, higher organizational commitment (Allen, 2006), increased ability of organizations to attract and retain effective employees (Podsakoff et al., 2000), lower turnover and intention to leave the organization and absenteeism and reduced potential for burnout in workers (Chen et al., 1998; Chen, 2005; and Podsakoff et al., 2009). So it is essential to know about the determinants of this widely investigated topic. The present study is an attempt to examine the role of work-family culture and personality traits as antecedents of OCB.
