What is the name of your state (only U.S. law)? I'm in California and i worked at a big retail company. I was written up for opening up a register while a cashier was not present. This was something I did on a daily basis for 7 1/2 years as well as my other co-workers in the same position which still do till this day. My manager was well aware that this is what we did everyday but I was the only to get in trouble for it. Even at other stores with the same company it happens and yet no one has not been in trouble for it. Would I have a case?
