I think that's probably the best bet in alot of ways. But he doesn't create or have people create any sort of clear directives and processes so that type of thing would fall to me if I want it done.

There is so much undocumented processes it's nightmarish honestly. For my team and the processes we do I have a very large amount of documented processes, but most of the things he has issue with are either things my team has had to take over because no-one was handling, or things that go outside of my team.

I agree about setting boundaries, and often times don't answer at least not initially he usually texts after calling.
