You don’t have to like everyone you lead. You do have to be fair to every one of them.

Liking people is not a requirement, and it cannot be faked for long anyway. Fairness is a different thing entirely, because it is about what you do rather than what you feel, and it is the part people can check. The test is whether somebody you find irritating gets the same minutes, the same hearing and the same benefit of the doubt.

Think of the person on your team you least enjoy, then look at how they have actually been treated this month. If they have been getting less, correct it quietly. You do not have to become friends to be straight with them.
