One area of the contract that I didn't hear discussed much was early retiree health care. According to the IAM site, "Retiree health care remains protected for 10 years" and "Retiree medical plan contributions continue under current contract provisions. However, the same changes that apply (increased co-pays, deductibles, etc) will apply to retiree medical."
Although I'm was in SPEEA rather than IAM, this is big for me, as I currently get very good health coverage for myself and DW for $40 per month. Hope that will carry over the SPEEA contract that will be negotiated in a few years.
