two management theories proposed by Douglas MacGregor to explain the nature of motivation and human behavior in the workplace. Theory X suggests that employees initially dislike work, avoid responsibility, and are prone to laziness if they are not under strict control and are not subjected to extrinsic motivation based on punishment and rewards. Theory Y assumes that employees are able to take responsibility, strive for achievement, and strive for innovation and development if they are provided with a supportive, stimulating and interactive work environment. This theory provides a starting point for understanding appropriate leadership styles and how to create a work environment that reflects the psychological and motivational needs of employees.
