Try reading the blue paper the pension fund sends you every year. Last year was in the neighbourhood of only 75% funding, and with the markets crashing the way they have, you'll be lucky to have 50% funding in the pension fund. And that's Ford !! GM is in much worse shape financially, and in the pension liablility.
You're also forgetting that retirees still get our benefits, so they are covered for semi private coverage like you, and other benefits we have over and above the Ontario Government Drug Plan.
