You guys are shooting yourselves in the foot. Millennials don't expect pensions to be around, and we're not counting on social security either. We won't feel sorry for you guys failing to save.
These were the same sentiments that were around when I first started too. I'm now retired, and both are still around.
The only way you can screw retirees is if that is part of the proposal. It's not likely the union would propose it and it's not likely that those about to retire would accept it.
You can't just decide that you don't like what happened, therefore I'll screw retirees. It just isn't that simple.
If this contract passes, it wouldn't be solely because of protecting pensions. A large part of the reason would be that younger guys don't vote, are afraid of a strike, or just don't care.
