After reading the mail from PCS... which I must admit, made me more inclined to vote NO just because I hate feeling I'm being "persuaded" by a biased argument. The TUs should not be pushing people to vote either way, just informing of facts and leaving us to our own free decision.
However.... one thing I think it's important to mention. That's 18 months of discussions between a team of senior managers, including highly experienced accountants and negotiators, with a support team of professional pensions analysts... taking on a team of union officials that are actually office workers, controllers, engineers etc etc. Not to say the guys in the TU who sit on the pensions committees aren't intelligent and well informed... but the professional experience and the qualifications to speak with authority on these subjects is heavily weighted on one side. It's not surprising in such a position, that people can be persuaded in to an opinion they would previously have recoiled in horror from.
