Organizational Citizenship Behavior

Organizational Citizenship Behaviors (OCBs) are a special type of work behavior that are defined as individual behaviors that are beneficial to the organization and are discretionary, not directly or explicitly recognized by the formal reward system. These behaviors are rather a matter of personal choice, such that their omission are not generally understood as punishable. OCBs are thought to have an important impact on the effectiveness and efficiency of work teams and organizations, therefore contributing to the overall productivity of the organization.
Dennis Organ of Indiana University is widely credited with introducing OCB in academic literature. In the last three decades, it has grown to become a prominent stream of research.
Scholars hold different views with respect to the dimensionality of OCB. Smith, Organ, and Near (1983) conceptualized OCB with two dimensions: altruism (behavior targeted specifically at helping individuals) and generalized compliance (behavior reflecting compliance with general rules, norms, and expectations). Later Organ (1988) identified five dimensions belonging to OCBs: Altruism, Courtesy, Civic Virtue, Conscientiousness and Sportsmanship. Largely based on Organ's (1988) five-dimension taxonomy, Williams and Anderson (1991) proposed a two-dimensional conceptualization of OCB: OCB-I (behaviors directed toward Individuals; comprising altruism and courtesy) and OCB-O (behaviors directed toward Organization; comprising the remaining three dimensions in Organ's (1988) conceptualization). Some scholars also have utilized a unidimensional or overall OCB measure in their research (e.g., Decktop, Mangel, & Cirka, 1999). A most recent meta-analysis conducted by Hoffman, Blair, Meriac, and Woehr (2007) suggested that "current operationalizations of OCB are best viewed as indicators of a general OCB factor..., there is likely little to be gained through the use of separate dimensional measures as opposed to an overall composite measure" (p. 562). A similar conclusion was reached by a previous meta-analysis (LePine, Erez, & Johnson, 2002).
Type of organizational citizenship behaviors:
Altruism (Helping): is selfless concern for the welfare of others. helps others who have been absent, or helps others who have very high work loads.
Courtesy: Take steps to try to prevent problems with other workers.Does not abuse the rights of others.
Civic Virtue: Attends meetings that are not mandatory, but considered important.Keep abreast of changes in the organization.
Conscientiousness: Does not take extra breaks.Obey company rules and regulations even when no one is watching.
Sportsmanship: Does not consume a lot of time complaining about trivial matters. Focuses on the positive side rather than what’s wrong.
