Pros
With the high turnover, eventually you will get the hours ( shifts ) you want. You can advance from Tier 1 to Tier 2 easily. But switching to from any other departments is difficult. Work with many people, friendly. If you meet metrics you can bonus and that can add up to hundreds of dollars each month on top of your hourly pay.
Cons
The only way to be successful is to respond to callers in a repetitive fashion. Otherwise you get too caught up in trying to explain why the rules are the way they are. If you are old school customer service this is too difficult. You have to balance your time in the escalation position between customers and dealers, and the dealers call YOU for the wrong things and it eats your time to do your real job. The other departments / managers that should be assisting these dealers either don't know how, or won't give the time to assist. If you can be freakishly cold to the people you speak with, you can succeed -- meaning keep your job AND get the bonuses.
