Organizational behavior is the study of how individuals and groups act within organizations and how organizations manage their environments. It aims to understand and predict employee behavior, improve productivity, and facilitate change. There are several models of organizational behavior, including autocratic, custodial, supportive, and collegial models. The autocratic model relies on power and obedience, while the custodial model focuses on economic resources and security. The supportive model emphasizes leadership and employee motivation. The collegial model is based on teamwork, shared goals, and self-discipline among team members. Organizational behavior provides insights to help organizations and individuals within them be more effective.
