Seems like it would be simpler to ask your direct reports to inform you when a meeting is called between one of them and somebody in another department. Then you can just show up and document things.
So it would mean a lot to you to be there?
While I know what you’re referring to, your comment makes no sense.
Your request makes you sound like a micro manager. Micro managers typically don’t rise very far in leadership. Instead of trying to oversee every aspect of your teams work, why not just set expectations and when they don’t meet them, hold them accountable. The people that fall below expectations should be let go or moved to roles they can be successful in.
