Suddenly we now work overnights. I am not functioning well on this schedule, my sleep is messed up, my mood is whack, my body doesn't know when to eat. The duties of job changed and I'm not trained in this kind of new work. Turns out it's legal to just change employees hours and duties. I make pretty good $$ but I can't have my labor and my time and sanity exploited like this. I got a new job, more money, stable duties, great benefits. I'm dropping my resignation letter the moment I come back from vacation.
