Organizational Citizenship Behaviour (OCB) has been signified as one of the antecedents of organizational
effectiveness. OCB is widely studied over the years in the US but has received relatively inadequate attention in
other Asian contexts. This study explored and examined number of predictors of OCB in the Arabic-speaking
context (Saudi Arabia in Gulf). The data was drawn from 275 employees of both private and public banking
sectors. Predictors of OCB examined are Job Satisfaction and Organizational Commitment, Role Perceptions,
Fairness Perceptions, Leadership Behavior, Individual Dispositions, Motivation and Feedback. The results found
support the hypotheses stating the positive relationship between the predictors of OCB and organizational
citizenship behaviour except motivation that found no relationship with OCB. Implications for future research
are discussed.
