"Well, I had a boss who was not acting according to our values. It was clear they were going through some personal issues, but that's no reason to take it out on your customers or team. On one occasion, this person was berating a teammate, and I stepped in and told this supervisor to take a step back and compose themself before they continued this dialogue. I remember saying that this was not a good look for them and that they were hurting their reputation as an effective leader. They threw a few words my way, and I responded by repeating myself. The rest of us then disengaged. Later, they apologised to the group and took some time off on leave to deal with the problem. When they returned, they seemed more themself again."
