Most don't.....unless they hire me. Seriously, it's what I do as a consultant. It's easy really but too many companies don't want to spend any money at all because they don't see the backside value to keeping a customer. And lots of companies like to introduce spiffs and bonuses for people like call center reps for things like answering the most calls or short talk times. I'm sure you can see the folly in that approach.
I don't answer the phone fuckstick (thank you @tirk), I captain the ship. You may now bow down and kiss the ring.
