Organizational citizenship behavior (OCB) is a newly emerging concept in the literature of organization
behavior. Despite an increasing number of studies on Organizational Citizenship Behavior (OCB), no unifying
work is focused on the measurement of degree of change in OCB in a public sector organization and a private
sector organization. We hypothesized that there is a significant difference in the degree of OCB of employees in
public sector and private sector organization. Data were collected from 200 employees consisting of managerial
and non-managerial staff from both the public sector and private sector organizations. The results showed that
employees in public sector organization have greater degree of OCB in comparison to private sector
organizations and also the job satisfaction increases or decreases based on increase or decrease in OCB. The
purpose of this study is to invoke Organization Citizenship Behavior in private sector organization. Obtained
result was in the line of the hypotheses. In terms of organizational citizenship behavior; a significant difference
is noticed between public sector and private sector organization. As expected, public sector employees have
exhibited higher degree of OCB as compared to private sector employees. Most importantly, organizational
citizenship behavior is being proven as the catalyst for enhancing job satisfaction level of employees.
