Correct Response: A. The equity theory is based on the idea that compensation should be based on what employees feel they contribute to the organization and should be equivalent to that of others who contribute in the same way. The equity theory is based on equal pay for equal work, and is not applicable across different levels of positions (B), or social equality (C). Managers listening to employees' thoughts and opinions in the decision-making process is an example of a participative theory (D), which is separate from and unrelated to equity theory.
