Human capitals are the best competitive advantage in organizations, and have been an important element in any organizational achievement. The reverse is also true. The human resource may be a serious obstacle against organizational effectiveness. In this article, we investigate the anti-citizenship behaviors, and examine the relationship of organizational stress, injustice, personality and culture, and anti-citizenship behaviors. Experimental results suggest that there is a significant correlation between organizational injustice and anti-citizenship behaviors. Hence, when anti-citizenship behavior is increased, the organizational effectiveness is extremely decreased.
