Where do I begin. First of all, the promise DOES NOT WORK. I have had customers tell me that they don't like when people bother them while shopping, which if you follow the promise, you will be doing. The promise is an extremely uncomfortable sales model especially if you struggle with social anxiety, especially because you are forced to "add-on" in the fitting rooms. Most of the time the customers don't even try the outfits you give them. If they wanted my help they would ask, and I have no problem giving them assistance.
Hours are bad. You either get too many or not enough, as the turnover rate is awful. I worked at my location for 6 months and I had been the employee with that store the longest. The scheduling is very inconsistent and schedules are often made only a day or two in advance. If you need to call out/switch shifts, good luck finding any coverage.
Upper management/ CEO's do anything to save a buck, including making you close the store alone, which if you work in a mall, can feel unsafe. I also have no idea how they complete their hiring process, because it amazes me how certain coworkers I have had were hired in the first place. There is also definite favoritism when hiring.
Pay could also be way better, as if you have terrible management you end up taking on their responsibilities anyway.
There is typically not much to do in store, making shifts go by very slowly.
If any of this didn't turn you away, three people at my location resigned within a week of each other.
