Dreading/hating going to work

I have worked at this place for 3 years and I used to love it, but the old owners sold and new owners are nice but everyday it’s something. They can’t keep anyone hired, they are giving me hours based on who needs off when and I get “called in” every time someone calls in.

(Those are just some of the minimum stuff that annoys me; there is plenty more)

But, I hate waking up on work days, I get this feeling in my stomach and just HATE going. Is it time to look for another job?
