Frustrated

Hi, disgusting.

When I used to manage staff, some of the team members were supervisors who didn’t get along with each other. My first strategy was to give them some time offline (away from the staff they supervised) to work it out by themselves. Sometimes it worked and sometimes it didn’t. When it didn’t, that’s when I actively stepped in and mediated. I made it clear that, while I understood that disagreements were inevitable, their roles were to work with each other. As the boss, I gave ground rules as to what their specific responsibilities were. I also let them know that their jobs were to lead the operation; not hinder it by in-fighting.

If you can’t work it out with the other person, then perhaps your manager can help. You were probably chosen for a leadership position because your boss was confident in your abilities and performance. It might be in your manager’s best interest to end the conflict so everyone can perform the jobs that they’ve been assigned.
