Thanks so much for your answers...it's basically career security and the restoration of my pension which I lost via the company filing for bankruptcy.
I'm tired of having to read about my career security in the newspapers...seems that UPS is a very profitable company over the prior decades.
Other issue is the possibility of recouping the pay I'd give up to come to UPS; my present airline pays there Captains UPS F/O year 5 wages!!
...and of course, my prior life was C141's so I'm proud to be re-associated with my prior professionals.
