Pros
Great place to work, staff were always a good laugh at the Brighton store. Ideal job for uni students. Pay on the lower side (compared to other high street retailers) but staff discount one of the best. Offer <10 hr contracts which is ideal for students.
Cons
Unless you've lost a limb, expect to be interrogated upon calling in sick, or made to feel like you're letting the team down for not going in. Pay lower than some other retailers. Not sure if still the case, but "level 2's" (i.e. one above sales assistant, one below manager) get paid about 15p more an hour than the standard sales assistant. This being said, pros definitely outweight the cons if you are just looking for a part time job at uni. If you are pursuing full time career in retail, look elsewhere.
