As a night shifter, occasionally this is a perk. You can get simple questioned answered the same day, and if there is ever some kind of policy issue it can be brought to their attention relatively easily. To say nothing of an emergency situation where you need someone above shift supervisor, management may say call them in an emergency but they never answer their phone at 3am but god forbid you don’t pick up on the third ring at 2pm when you’ve been asleep since noon.
