Cons: Customers - imagine there's a race of people called customers and you're hella racist. Because you will hate then, they will hate you. Not all the time of course and some will be nice but... There will be days... ACW (after call work) - this metric is usually about 20 seconds that you have to meet. If workforce is doing their job maximizing resources, this is (at most) the time you'll have between calls.
High stress envicroment - even if it's not sales oriented you'll still have average handle time metrics, hold time metrics, and call review scores to deal with. It's not hard, just annoying. Everything you do is under a microscope. That in addition to taking call after call after call leads some folks to burn out. Accept that going in. That tone that indicates you have a call beep - I've been outta the center and started truck driving fairly recently. I still have dreams of that tone. I hope it fades as time goes on.
