I really doubt a UAL Furloughee is going to take a CAL recall and then switch over to UAL.....WHY? You get your old payrate when you got the AX from UAL...so if you take the CAL recall you will be flying a BOEING and not a damn Airbus as a LCC slave--Pay would be the same.
I am waiting to take the CAL recall.....and I have ZERO intention of going through school TWICE ...."just to screw management"
I'm a 99' UAL Furloughee---Twice!
