When we went to work for Kodak, we signed a contract that outlined our NDA obligations and Kodak's obligations in therms of "valuable consideration" in return for our work. Valuable consideration was outlined in terms of pay, retirement and medical benefits. Over the years, all of this changed as Kodak changed. They added and then removed dental benefits and they added insurance benefits. So, the plans changed gradually. There was never a hint that they would stop. In fact, at one time Kodak added some procedures in their bylaws that would prevent a buyout / split by some takeover corp.
Today, letters were received by all retirees covering what is going on. It stated clearly that there will be no health care enrollment this year. I suspect that our carrier will notify us of what comes next.
