You're not working for them anymore, so how is it abusive? You do plan to actually sell things and not just collect a paycheck and take up space, right? Find an establishment that offers merchandise you can sell without trouble. They don't all require high heels. I had twenty years of experience in retail, and I know this for a fact.
Of all the reasons I can imagine not to vote, the employment policies of private companies don't even make the list.
Everyone wants to work in a posh boutique, until they've actually worked in one, and figured out they might come out ahead financially by, say, selling major appliances at Best Buy. Where, incidentally, you can work in sneakers.
