The Japanese used to negotiate until demands got rediculous like this. They handled it by agreeing to the terms making the other side feel like they have accomplished something then about 90 days later they would close the facility and move the business elsewhere.
I am currently in contract negotiations with the USW and can tell you that they feel very empowered by what has been happening on the labor front here lately. They are taking the same path as the UAW.
They don't play. There is a Japanese owned car lock plant in Selma and it was well known to all that if you work there and quit, no matter how good of a worker you were, there is no going back. That was a very staunch policy they had and never veered from it.
