This comprehensive text provides a detailed review and analysis of the building-block theories in Organizational Behavior. Expanding on his previous work in the field, John Miner has identified the key theories that every student or scholar needs to understand to be considered literate in the discipline. Organizational Behavior: Essential Theories of Motivation and Leadership analyzes the work of leading theorists. Each chapter includes the background of the theorist represented, the context in which the theory arose, the initial and subsequent theoretical statements, research on the theory by the theory's author and others (including meta-analysis and reviews), and practical applications. Special features including boxed summaries of each theory at the beginning of each chapter, two introductory chapters on the scientific method and the development of knowledge, and detailed and comprehensive references, help make this text especially useful for graduate courses in Organizational Behavior and Industrial/Organizational Psychology.
