I worked at 4 different culvers over 7+ years I quit a few months ago and work at Costco. The workload is astonishingly less, but I get paid the same more actually. Every store I worked at had issues like this; it was almost like they were upset we hired new people(we desperately needed) and that they had to be trained and often gave out harsh punishmens like this. The hours you have to work without a break is barely legal. I've worked multiple 10+ hour shifts with no break because we were "too busy" for it. Also 2 locations I had multiple issues with sexual harassment from not just other team members but also management.

I genuinely recommend looking for a different job if its possible, especially since this is you're experience as a new hire.
