This document discusses power and authority. It defines power as the ability to influence or control people and resources. There are several types of power, including coercive power (using punishment), legitimate power (from one's formal position), reward power (using rewards), referent power (from admiration or respect), and expert power (from one's knowledge or skills). Authority is defined as the legitimate right to influence others and can come from tradition, common law, or being delegated from a higher level in an organization. Effective use of authority involves being polite, explaining reasons for requests, addressing concerns, and using one's legitimate position of power.
