Pretty much.Huh? My understanding is that Toyota/Honda provide just as much as GM to keep the unions out. Not the other way around.
The Japanese plants don't have a pension plan though (if my understanding is correct). I've been told that they set up each employee with an RRSP account that they contribute to (as does the employee). It's the one big difference.
One thing I do know that no company today wants to be on the hook for a pension that they could end up paying a guy every month for for 40 years. They'd rather just go the RRSP route and if you chew through the money, too bad for you.
Most bigger companies are operating this way today. Too much "obligation" otherwise.
