This document discusses power and politics in organizations. It defines power as the ability to influence others to act in ways they otherwise would not. Power comes from sources like rewards, punishments, authority, charisma, expertise, and information. Politics involves using power to influence decisions and achieve preferred outcomes when the results are uncertain. Politics exists in organizations because people have different goals, resources are limited, and outcomes are not always clear. This leads to coalitions, disagreement, bargaining, and a need for power and influence to determine winners and losers.
