Re: Interesting... color me skeptical.
> f your family is settled... relocating every 2 years, assuming that IBM is going to cover all of the costs... is still going to be a deal breaker for the older employees. (Try buying and selling homes every 2 years....) (Assuming you can't find another project in your current area. )
As an army brat, I had to deal with this for 16 years.
It's not an uncommon situation. However, at least in the military case you join up knowing that's the situation, and if you marry someone in the military you are (or should be) aware of it as well. Although It's a bit different being forced into it 15 years after you started!
Note in this situation you don't usually purchase a house each time you move, you rent.
