My team was approached today by our manager.
Background: We have a hostile co worker. He's aggressive, sarcastic, rude to clients and managers. About 4 months ago he out of the blue stopped talking to the team. We asked our manager if everything was OK. She advised us that he was going through personal things and needed some space. We all gave him his space.
Fast forward to today: My entire team was dragged into a room minus the hostile co worker. We we're advised that hostile co worker was feeling isolated and if we didn't start incorporating into the fold he was calling HR. We all released our frustrations about the hostile co worker.
To sum it up, our manger stated if we don't incorporate him our team will not grow (we're a small unit looking to expand) and our head manager will not be happy if HR is involved.
This is in Rhode island. Any suggestions?
