Management
Hr
They like to pile on more work and no more pay
If you do your job good you get to do other people's jobs too.
Don't try to move up because they will tell you you're not qualified then hire someone off of the street with zero knowledge you have to train.
Management will not work with you if you have any family issues. You will be replaced if you can't work the shift requirements. They have random overtime that is required to work.
