I used to about 4 years ago. I got paid $8.50/hr to throw boxes as fast as i could. Which was never fast enough. also in the begining i was on call, for the 4-8am shift. Nothing like working all day, going out till last call and getting home to find a message on your machine that you need to show up to UPS in 5 min. Might be why I didnt last, but drivers make great money. Just something to think about.
