Final answer:
Bill exhibits Theory X managerial qualities by emphasizing close monitoring and control of employees in the grocery store.
Step-by-step explanation:
Bill, the supervisor at a grocery store who monitors employees closely and reprimands them for talking when no customers are present and for taking longer breaks than allowed, most likely uses Theory X assumptions when dealing with employees. Theory X is characterized by the belief that employees are inherently lazy, need to be closely supervised, and that control and punishment are necessary to achieve organizational goals. In contrast, Theory Y is based on the assumption that employees are self-motivated, seek satisfaction in their work, and function better when they have input in decisions and are allowed some autonomy.
