The document is a chapter from an organizational behavior textbook. It outlines several theories of motivation: Maslow's hierarchy of needs, McGregor's Theory X and Theory Y, Herzberg's two-factor theory, McClelland's needs theory, goal-setting theory, equity theory, expectancy theory, and theories of intrinsic motivation. The chapter objectives are to introduce these theories and explain how they complement each other in understanding what motivates employee performance and behavior.
