This chapter discusses work motivation from three approaches: the individual differences approach, the job and organization approach, and the managerial approach. It provides learning objectives on factors that influence employee motivation, how goals and rewards can improve performance, and how job content and organizational context affect motivation. The chapter also summarizes several theories of motivation, including reinforcement theory, Herzberg's two-factor theory, Hackman and Oldham's job characteristics model, equity theory, Maslow's hierarchy of needs, ERG theory, and the integrative expectancy model. Managers are provided guidelines for improving employee performance and motivation.
