Organizational citizenship behavior

In industrial and organizational psychology, organizational citizenship behavior (OCB) is a person's voluntary commitment within an organization or company that is not part of his or her contractual tasks. Organizational citizenship behavior has been studied since the late 1970s. Over the past three decades, interest in these behaviors has increased substantially.

Organizational behavior has been linked to overall organizational effectiveness, thus these types of employee behaviors have important consequences in the workplace.

Dennis Organ is generally considered the father of OCB. Organ expanded upon Katz's (1964) original work.
