In withholding your recognition of another person’s contribution to a team’s success, you are not only sowing injustice and treating people unfairly but you are depriving people of the emotional payoff that comes with success. They cannot revel in the success or accept congratulations—because you have choked off that option. Instead they feel forgotten, ignored, pushed to the side. And they resent you for it. If you really want to tick people off, don’t recognize their contributions.
