Just throwing my two-cents into it -- night shift sucks. At my workplace, we instituted a third-shift for the specific purpose of performing receiving and bulk product putaway functions that otherwise clog up the warehouse and make the process of filling orders too complicated. The number of equipment accidents on that shift (11PM to 7:30AM) is astronomical compared to the number of accidents the rest of the hours of the day combined.
I have long decided that working the night shift would be "wrong livelihood" for me. Maybe it works for some people, but I'd be half alseep at my desk, or worse, on an 8,000 pound piece of equipment.
I would inform your supervisor that if there isn't a possibility of moving to a daytime shift at your current place of employment, they should expect you to find employment elsewhere. I know.... easy to say in my position, much harder to do.
Whatever you do, may you be well.
