Organizational behaviour is the study of how individuals and groups act within organizations. It examines how organizations function and how we can understand, predict, and influence events within them. Key trends impacting organizations include globalization, a more diverse workforce, changing employment relationships like an emphasis on employability over job security, the rise of virtual work, and a focus on workplace values and ethics. Organizational behaviour draws from multiple disciplines and uses systematic research methods and multiple levels of analysis to understand organizations as open systems that interact with their external environment.
