This document discusses power and politics in organizational behavior. It defines power as one's ability to influence another's behavior according to one's wishes by controlling resources the other needs. Power comes from formal positions in a hierarchy as well as personal attributes. The greater one's dependency on another's resources, the more power that person wields. Coalitions are groups that temporarily form to achieve influence. Politics in organizations involves influencing advantages through activities beyond one's formal role, which can be either legitimate or illegitimate.
