Grounded in research but balanced with applications, this text focuses on productivity and performance. It employs a scientist-practitioner model to show how theories develop through research, followed by practical examples drawn from the business world to demonstrate the application of the theories. The third edition contains new information on: Interviews (Chapter 3); Personality Assessment (Chapter 4); Organizational Commitment (Chapter 8); and Organizational Citizenship (Chapter 12), as well as new coverage of affirmative action, downsizing, 360 degree feedback, psychological contract and e-mail.
