Final answer:
The correct answer is d) Employees are solely motivated by financial rewards, which is not one of the takeaways from equity theory, indicating that motivation includes a range of factors beyond just financial rewards.
Step-by-step explanation:
The option that is NOT one of the three takeaways for managers from equity theory is d) Employees are solely motivated by financial rewards. Equity theory posits that employees are motivated by a desire for fairness in the workplace, which includes fairness in the outcomes they receive for their inputs (effort and work) and their comparisons of these outcomes to those of their peers. While financial rewards can be part of what motivates an employee, equity theory suggests that motivation is also strongly influenced by the perceived equity or inequity of those rewards. Workplace motivation is complex and includes factors such as recognition, opportunities for growth, and the sense of being valued and treated fairly.
