💡 The sales manager's primary motivation to remain in her job is the high bonuses she earns, which are an example of an extrinsic reward. Extrinsic rewards are external incentives, such as monetary compensation, bonuses, or other tangible benefits, that motivate individuals to perform a task or stay in a role. In this case, the manager is staying in the job despite the stress because of the financial rewards she receives. Explanation of Incorrect Options: A. Intrinsic reward: Intrinsic rewards are internal motivators, such as personal satisfaction, enjoyment, or a sense of accomplishment derived from the work itself. Since the manager is motivated by bonuses (external), this is not the correct answer. B. Job enrichment: Job enrichment refers to redesigning a job to make it more engaging or fulfilling by adding responsibilities or opportunities for growth. The scenario does not mention any such factors. D. The hierarchy of needs: This refers to Maslow's theory of motivation, which includes levels such as physiological needs, safety, belonging, esteem, and self- actualization. While financial rewards could address lower-level needs (e.g., safety), the specific focus here is on the external reward (bonuses), making this option less precise.
