I think you are getting a little ahead of yourself. This thing is far from settled. Honestly, I wouldn't worry about it for now. Who knows, the LOA might actually get 50+% of the vote. I doubt it, but you never know.
I believe the FDA deal needs to be settled then a system bid before any newhires join FDX. We are talking several months here, maybe 08 before this gets done.
Also, keep your eyes on current legislation. The hiring outlook is far more dependent on Age 60 than a HKG/CDG domicile.
