Well, considering the host of guys willing to waive a retirement check for the chance to work five more years, I'd say its going to be an uphill fight.

How much would a company pay me to work until 60 then "beat it" with zero benefits? You know that's the company's target, and this age 60 thing is the nose under the camel's tent. They'll grandfather a few benefits, but the B plan will be the first target, the the whittling of the A plan will follow.
