Abstract
Antecedents of Organizational Citizenship Behaviour were studied in the banking sector in India. The antecedents of OCB include Altruism, Conscientiousness and Civic Virtue in the study. Causal research design was adopted and purposive sampling was used. Unit of analysis was middle level managers and employees in private banks. 50 Questionnaires were analysed from different branches to study the relationship of OCB and its impacts on new generation private banking sectors. Results indicated that Civic Virtue explained more variance towards the construct of OCB compared to Conscientiousness and Altruism. In the current high competitive environment, where organizations are looking for those which can help them in achieving competitive advantage, OCB may help them. OCB is important for effective functioning of an organization because its ultimate goal is to make all the employees work towards achieving the organization goals rather than accomplishing their duties.
