I would coach this person, give feedback and offer them an opportunity to modify their behavior. I would have specific praise for what he/she does well and explain why it is important to improve interactions and work as a team, talking through specific examples of their actions/behaviors that need to change. I would ask the employee to come up with an action plan, review it together and continue to coach.
I would ask the employee to complete a free personality assessment like 16 Personalities or the Keirsey Temperament Sorter. That awareness should help the employee understand others and how their type/style is perceived by coworkers. Actually, it might be a good team activity at a later date.
If the employee does not improve, then it’s time for the door. You tried, and you have documentation to warrant that action. I hope this helps!
