May be just the beginning. Given the status quo, and hiring/retirements at the big three + FDX, the math favors leaving if you're under age 55 and are not a line-holding CA.
If you're under 40, I think the math says leave, period.
* Unless you're totally adverse to short-term furlough risk in the interest of long-term gain. Or absolutely must drive to work in PDX.
