Most of the sales floor managers are extremely rude and demeaning, except for one. If you don't know something, they'll sound annoyed and talk to you as if you're stupid. I spent several shifts holding back tears because of how stupid one manager made me feel. It doesn't matter if you're new; you're expected to know everything already.
There is extremely poor communication; everyone will give you a different answer. I once asked 5 different coworkers -- who had been working there since it opened -- where to put the rag-offs (unsellable items to be destroyed) and nobody could give me an answer. This happened repeatedly, and was very frustrating.
There is no schedule printed for everyone to view. They print out little personal schedules for each employee. Three times, they didn't print out mine, and they were annoyed at me for asking them to print one. They also won't tell you when your break is, so you have to ask them, and they get annoyed at that, too!
Customer service is supposed to be stressful because of the customers, not because of your employer. If the management changes, this might be an okay place to work. Otherwise it's just constant walking on eggshells.
