Pros
Escaping to the toilet whenever you can. Getting to go home at the end of the day (although the managers have probably clamped down on that now too). The prospect of death and never ever having to set foot inside the place again.
Cons
If you're on the phones, you'll be micro-managed to within an inch of your life. If you're back office, you'll be treated like a second class citizen (or worse) by the rude, aggressive managers. Team members who make it up the ladder to become team managers generally become different people who would throw you under the nearest bus to make themselves look good. Managers couldn't care less about you and will treat you like the payroll number you are. Work-life balance is non-existent, and you'll be treated with contempt if you, god forbid, have a life you need to live outside of work. Forget job satisfaction and/or the feeling of accomplishment. Most of the managers can't spell their own names but are quick to critique staff on any aspect of performance they see fit.
