Alfaro - You don't need to apologize, nobody got "angry". A lot of guys, both UPS and FDX, are trying to give you some advice from first-hand experience. Money is fine, but folks are telling you that you can do just as well as FDX, and for a much more enjoyable work life. Believe it.
And believe it or not, after 21 years here at the brown paradise, I would leave in a heartbeat if FDX or Cathay, or Cargolux or possibly a few others would hire me. I am NOT kidding you. I am flying worse schedules here than I was 20 years ago. It gets really, really old. I'm far too old now for them to hire me, but I would gladly take a pay cut not to have to put up with this acrimonious environment the rest of my career.
