Miller, by taking such a visible and hard line, may have underestimated the UAW. The union would like to see a settlement, but not at the cost of 60 years of gains.
There are some very hard choices and no easy answers. This is a long way from over.
I suspect they felt that taking a very hard line would send a message to the union. Instead the message that they sent was to dig in your heels.
This is the first pitch in the game of hard ball and I think the union is both angered and not by any means intimidated.
