So wondering if you mean 2nd or 3rd shift. And for those wondering 1st shift is the "day" shift. Where your start time is ~8 AM and then you end ~3 PM. Then 2nd shift is where you start at ~3 PM and end at 11 PM. And then finally 3rd shift is where you start at ~11 PM and end at 8 AM.
As you can see there is a BIG difference between 2nd and 3rd shift and what someone might call a "night" shift.
