Don't really see a problem. When 92% of the workforce says no, then clearly it was an unacceptable contract. Hopefully they thought long and hard about the alternatives if the plants were closed, but taking an 8% pay cut and cessation of payments into their pension plan is a fairly big hit they were being asked to take.
I love the attitude of so many on here who seem to basically support employers no matter what they do. I'm hardly a die-hard labor supporter, but some of you guys are over the top.
