The document discusses power and politics in organizational behavior. It defines power as one's ability to influence others, and differentiates it from leadership which focuses on downward influence to achieve goals. There are two sources of power - formal and informal. Formal power comes from one's position and includes coercive, reward, legitimate, information, and expert power. Informal power includes referent power which comes from loyalty and respect. Organizational politics arises from individuals' and ambiguous organizational situations, and can generate both legitimate and illegitimate political behaviors.
