The document discusses several theories of motivation:
1. Content theories examine what motivates people, such as Maslow's hierarchy of needs theory, ERG theory, and McClelland's acquired needs theory.
2. Process theories look at how people are motivated and make work-related decisions.
3. Herzberg's two-factor theory proposes that different factors cause satisfaction versus dissatisfaction at work. Satisfiers like achievement motivate, while hygiene factors like salary prevent dissatisfaction.
4. McGregor's Theory X and Y describe different views of employee motivation, with Theory Y assuming employees want responsibility and are self-motivated, leading to better performance.
