Pros
Good for a part-time/temporary gig. Culture was good at my store. Good co-workers. If you don't mind not being able to plan your life around you work (schedules are computer generated every week, and you schedule can vary widely week to week). Other pros: benefits even as a part time employee
Kontras
This used to be a good career (union had more backbone 15 years ago). Under the new contract, you are never guaranteed full time or a set schedule, holidays are not paid double time anymore, and Sunday premium went away (or reduced to $1 extra). Your schedule changes every week, even with 20 years experience. Culture depends on your exact store. Some stores are toxic. Visit the store as a customer before you accept the job. See if the employees look like they are always pissed off. If they do, that's a bad sign.
