Final answer:
Theory X and Theory Y are the two theories that concentrate on managers' attitudes and assumptions about workers. Theory X assumes that most people dislike work and need to be controlled, while Theory Y assumes that people seek inner satisfaction from work and can be motivated with responsibility and involvement.
Step-by-step explanation:
The two theories that concentrate on managers' attitudes and assumptions about workers are Theory X and Theory Y. In Theory X, managers assume that most people dislike work and are not self-directed. They believe that employees need to be controlled and punished to achieve organizational goals. In contrast, Theory Y assumes that people seek inner satisfaction from their work and can work productively when given responsibility and involvement in decision-making.
