The company I worked for switched to DC a couple years ago for new hires. Union didn't like it much but they did it anyways. I just made the cut off for the DB plan, good thing in theory but who really knows what the plan will look like in 40 years when I need it.

For entertainment if you want to see an example of a rather badly managed DC plan, check this out. CA can't go bankrupt though like the US airlines so the tax payer makes up all the losses they manage to generate.
