It's an immediate upgrade over "book monkey", but the stress and being a bitch absorber doesn't seem to be worth it. And I don't start immediately since I have to do a course, that turned me off a bit.
Is this an inbound or outbound call centre? Probably doesn't sound like it will make a difference right now, but it does.
Inbound call centres are premised on people needing something from you - so you'll have a fair contingent who start out nice but who become increasingly frustrated as you get farther into a script from which you cannot deviate.
Outbound call centres generally have higher turnover, because the string of profanities with which many callers are met makes them want to curl up and cry. You'll beg for the ones who just say "not interested" and hang up.
Parents of young children will swear a blue streak at old ladies just trying to make ends meet.
As an environment, both will track your time, in both you'll be call-monitored, and morale won't be high in either. But if you can stick with it for six months and get a recommendation out of it, and you'll be able to (rightly) claim that you've got superior client relations skills.
