Anecdotally I understand that Walmart has a serious employee theft problem.

But then, so does Anthropologie, a high-end retail "lifestyle" store where one of my kids is a supervisor. Her store does $50 to $80K/mo retail. They don't pay their floor staff much and even supervisors don't get a lot. They have a serious problem with employee theft and they also have a substantial turn-over.

Interestingly, they also have a huge problem with shoftlifting, both professional and "regular" customers. She says a lot of theft is from well-off customers who steal little things and big ticket things. Mostly for the thrill she thinks as they could afford to buy anything in the store.
