Wrong conclusion. This is a replay of Detroit. Boeing is just being a little smarter than GM, Chrysler and Ford were back in the 60's, 70's and 80's. Sadly the unions, with a lot of help from management, nearly destroyed the American auto industry, who couldn't see past the next short term contract.

What are the chances of IAM members being able to hold their union bosses responsible for the loss of thousands of Boeing jobs in Washington state, once Boeing decides to move its operations somewhere else?
Well, glad you asked. The chances of that will be 0.00.

Labor is a cost of business, just as is power, raw materials, waste disposal (you may not know who runs that business, but I assure you it ain't the Boy Scouts), transportation, taxation, and other things.

Nobody would find fault with relocating to a place where taxes or raw materials or power or transportation costs would be lower.

But just let you talk about moving somewhere because you want lower labor costs and fewer disruptions to production because of labor and watch the screeching and hysteria occur...
