The document discusses several theories of motivation:
1. Frederick Taylor believed workers are motivated mainly by pay and breaking work into small repetitive tasks. However, this led to worker dissatisfaction.
2. Elton Mayo found workers are motivated by social factors like interaction and attention from managers.
3. Abraham Maslow's hierarchy of needs theory proposes workers must have lower level needs met like pay before pursuing higher needs like fulfillment.
4. Frederick Herzberg argued motivators like interesting work that provides responsibility are more effective than dissatisfiers like pay. Methods like job enrichment and empowerment can motivate.
