Let day shift play their silly office politics. They don't pay me enough to be bothered by their crap. I was here before nearly everybody, with less than a handful of exceptions among a staff of 300+. There have been changes before, there will always be changes - and I'll still be here. And if I'm not, it shouldn't be to hard to find a similar job at another hotel. I've got over a decade experience in a field where the average turnover is six months or less.
Screw 'em, they're not worth the stress.
