Simply put, if your team member doesn’t respect you or her peers, why is she working there? Ask her if she wants to be working on your team. If she says she does, lay out what you expect, clearly and calmly. If she says she doesn’t, start the process to move her to another team, or help her leave the company. That’s it? That’s it. You can’t have a person working for you who doesn’t respect you, or doesn’t respect your team. It will eat away at the cohesion of the rest of the team as they wonder whether that person is right in not respecting you.
