I just finished reading another article on this at the Seattle Times that goes into it in more depth. Was written by Dominic Gates, Times aerospace reporter and talks of the 777 line in Everett.
The NLRB over stepped their authority when they tried to force Boeing to remain in Everett and limit expansion to other states and the union is Everett over stepped with their strike at the beginning of the recession, when airlines were struggling. I remember reading about the test flight that took place during that strike, the plane had to turn back to Boeing field due to metal shavings left in the gas tank, blocking the fuel lines. That sort of thing just doesn’t happen by accident on a test plane, produced by top level machinists. The unions can only blame themselves.
