Organizational behavior is the study of human behavior in organizational environments, as well as the interaction between individuals and the organization. This field is generally categorized into three levels of analysis: micro-level, meso-level, and macro-level. The micro-level focuses on individuals within organizations, the meso-level examines work groups and their dynamics, and the macro-level explores organizational behavior and structure at a broader level. Research in organizational behavior employs various methods, including both quantitative and qualitative approaches. Quantitative methods encompass statistical techniques such as correlation, meta-analysis, multilevel modeling, multiple regression, and structural equation modeling. In contrast, qualitative research methods include ethnography, case studies, historical analysis, and interviews. This book is a compilation of chapters that discuss the most vital concepts in the field of organizational behavior.
