Punishment and rewards are two sides of the same coin. Rewards have a punitive effect because they, like outright punishment, are manipulative. “Do this and you’ll get that” is not really very different from “Do this or here’s what will happen to you.” In the case of incentives, the reward itself may be highly desired; but by making that bonus contingent on certain behaviors, managers manipulate their subordinates, and that experience of being controlled is likely to assume a punitive quality over time.
