McGregor - Theory X / Theory Y
Theory X and Theory Y are theories of human motivation created and developed by Douglas McGregor at the MIT Sloan School of Management in the 1960s that have been used in human resource management, organizational behavior, organizational communication and organizational development. They describe two very different attitudes toward workforce motivation. McGregor felt that companies followed either one or the other approach. He also thought that the key to connecting self-actualization with work is determined by the managerial trust of subordinates.
