Understanding Organizational Behavior represents the solid scholarly foundations on which the science of organizational behavior was built, the realities of contemporary life in organizations, and the challenges that constantly present themselves. Our overarching theme of change is accompanied by four supporting subthemes: globalization, diversity, technology, and ethics. Each theme presents its own challenges and presents demands on individuals to learn, grow, and adjust. This text presents the opportunity to learn concepts, ideas, and theories that help enhance the management of human behavior at work.
