I was a manager of a warehouse for years on night shift. I had no bosses except for one hour at the end of my shift.

As long as we got our shit done I didn’t care what people did. They complained on days we weren’t doing stuff that would help their shift once we got our work done. The solution our shift came up with was making sure the guys timed their work to finish just before the end of the shift so they wouldn’t have any expectation to do day shift work.

They did some sweeping to pretend they were helping days but no actual extra work.
