I worked there three years ago as a night stocker and got threatened with less hours if I continued to "abuse overtime" - I accumulated three minutes OT in 40 hours. When a holiday comes around, you get paid for the holiday, but then are given only 4 days work.
I did it for beer money, enjoyed giving the managers $h!t over their petty crap and bailed when they wouldn't give me time off to visit relatives. "We didn't hire you for your convenience." That was understood. I told them it was a two-way deal - W-M got an employee who was always on time and never missed a day in three years (highly unusual) . In return, there was a tacit agreement that allowed me to take off the summer months (that worked for two years - then we got a new manager).

Which is exactly how one should react.
If one doesn’t like it, quit.
There are lots of people who need the job.
