Answer: Reward power.
Explanation:
Reward power is using rewards to make a worker follow an instruction and achieve organizational goals. In case of noncompliance, one can withhold the reward from the employee. Reward power is not a personal power but rather a formal power.
Reward power arises from the formal authority given to a person to give out rewards. Examples of rewards are company car, bonus, recognition, praise, gifts and pay rise. The positive reinforcement programs and pay-for-performance used by Nannette are examples of reward power.
