I recently started managing someone who I just cannot stand as a person. Like their voice is nails on a chalkboard to me and they also went over my head to say they didn't want to report to me like immediately after they were told to report to me. (My boss immediately told me and made fun of them for not having an alternative in mind). I like to separate the fact that I hate their guts from the work, but the work isn't all that great and they could easily be replaced.
any tips on how to manage this situation?
