Theory X and Y

two contrasting types of managerial philosophy: Theory X managers assume that workers are passive, lazy, and motivated only by money and security, whereas Theory Y managers assume that workers want to grow psychologically and desire autonomy and responsibility. It is hypothesized that these assumptions are self-fulfilling, so that workers who are subjected to Theory X management will act in a lazy and untrustworthy manner, and those who are subjected to Theory Y management and are provided with a workplace that encourages psychological growth will show creativity and initiative. A Theory X manager is authoritarian in leadership style, whereas a Theory Y manager is participative and democratic. [described by Douglas McGregor (1906–1964), U.S. management consultant and social psychologist]
