I see my manager as a "negotiator on behalf of the company" for work life balance. If I want to change something, I run it past them. If it messes something up they come back and say no and why. And I decide if it is worth it to keep working here. Or between us we come up with something else to keep both parties happy. At my workplace currently, management is pretty flexible and happy to go through whatever HR paperwork required.
