You give your pajama-factory workers a $5 raise (per hour), and you also praise them generously for their hard work. They promptly produce 50 percent more pajamas. You assume this is due to the raise you gave them. Instead, you may be experiencing: a. McGregor's Theory Y.
b. the Hawthorne effect.
c. Maslow's survival needs.
d. Self-fulfilling prophecy.

a. McGregor's Theory Y.

Explanation:

McGregor developed a a theory of motivation in the workplace.

Theory X is an authoritarian management battle where employees have little creativity and expect to be told what to do.

Theory Y is more participative. Employees take responsibility for their deliverables in an environment that encourages motivation.

Employee creativity is encouraged under theory Y.

In the given scenario the employees were praised generously. If this motivated them to produce 50% more Panama's, then we are experiencing McGregor's theory Y.
