The document discusses several theories of motivation that can be applied to managing employees and nurses. It describes Maslow's hierarchy of needs, Herzberg's motivators and hygiene factors, Vroom's expectancy theory, McClelland's need for achievement, affiliation and power, and McGregor's Theory X and Theory Y. The manager chooses these theories to understand what motivates employees in order to increase productivity. Maslow's hierarchy identifies physiological, safety, social, esteem and self-actualization needs that managers can help fulfill through compensation, benefits, recognition and challenging work.
