McGregor has 2 motivation theories. Those are, 
Theory X which means there assumptions about attribute are negative and the second one is theory Y which means assumptions about attribute are positive.

The assumptions of Theory X are ,
A mean employee intrinsically doesn't like work and tries to flee it whenever possible. Since the worker doesn't want to figure, he or she must be persuaded, compelled, or warned with punishment so on achieve organizational goals. Many employees rank job security on top, and that they have little or no aspiration/ ambition.
Employees generally dislike responsibilities. Employees resist change. A median employee needs formal direction. Etc

The assumptions of Theory Y are,

Employees can perceive their job as relaxing and normal. They exercise their physical and mental efforts in an inherent manner in their jobs. Employees might not require only threat, external control and coercion to figure, but they'll use self-direction and self-control if they're dedicated and sincere to attain the organizational objectives. If the duty is rewarding and satisfying, then it'll end in employees’ loyalty and commitment to organization. A mean employee can learn to admit and recognize the responsibility. after all he can even learn to get responsibility.
The workers have skills and capabilities. Their logical capabilities should be fully utilized. In other words, the creativity, resourcefulness and innovative potentiality of the staff is utilized to unravel organizational problems. Thus, we are able to say that Theory X presents a pessimistic view of employees’ nature and behavior at work, while Theory Y presents an optimistic view of the employees’ nature and behavior at work.
