This document discusses various theories and approaches for motivating employees, including: 1) Classical theories of motivation discussed include Taylor's scientific management, the Hawthorne effect, Maslow's hierarchy of needs, and Herzberg's two-factor theory. 2) Motivation can come from whether an employee feels their performance and effort will be rewarded and lead to desired outcomes. 3) Motivating with goals should ensure goals are specific, difficult but achievable, involve employee ownership, and provide timely feedback. 4) Jobs can be redesigned to motivate employees through greater skill variety, task identity, autonomy, feedback and personal growth opportunities like cross-training or job enrichment.
