Based on what I have read in the DBQ paper and online.
JD's spokesperson backed off her original Last & Best Offer statement to That is the Best Deal Economically JD will offer. IMO that means JD is still willing to revise the recently rejected offer, but the money won't get better. Workers are going to have to make decisions on what's more important- e.g. bigger pay bumps, but less rich benefits. Or more of this benefit, but less of another benefit.
It was also interesting in the paper that while the local union steward was still talking a lengthy strike. The 3 employees on the picket line interviewed were more pragmatic about the loss of their paycheck. And DBQ workers rejected the proposal 63-37%.
My prediction is the strike will be over in 10 days. And both sides will say they got what they wanted.
I tend to agree talking to people I know. There will be some that want to hold out and shoot for the moon, but they aren't the majority. The JD statement would indicate that anything more would take a lengthy holdout to get anything more. I don't think there's over 50% that will vote for a strike through the new year.
It just comes down to how eager the UAW will be to put this to another vote. They're already not popular with the local members, so forcing vote after vote won't help that.
