The behavioral management theory, also known as the human relations movement, emphasizes understanding human behavior in the workplace to enhance productivity, focusing on motivation, conflict, and group dynamics. Key theorists include Hugo Munsterberg, who applied psychology to improve hiring and employee behavior; Douglas McGregor, who presented 'Theory X' and 'Theory Y' to describe differing managerial assumptions about worker motivation; and Abraham Maslow, who developed a hierarchical structure of human needs that informs employee motivation strategies. These theories collectively highlight the importance of addressing human factors in management for effective organizational performance.
