Nomama, I'm not disagreeing with you. I think that this has issue has been misrepresented and oversimplified by all sides, each pursuing their own agenda. However, I'd disagree your point that everyone knows what already exists remains the same; in this thread, and in virtually ever other one on this subject, there are posters saying that they signed up to this however many years ago, and things shouldn't be changed.
The necessity (and desirability) of the changes themselves should be up for debate; I personally think that the previous arrangements were unsustainable, largely because of the increase in longevity, but it's clear that a lot of people either genuinely believe that the pension they've already earned has been taken away, or that there was some cast-iron unbreakable guarantee that nothing would ever change. That may well be the fault of the media (who I agree are shite at reporting this, but they're for the most part relying on soundbites and press releases prepared by others who are pushing an agenda), and I share your frustration that this is being misreported.
I wouldn't for a moment suggest that any worker, public or private sector, who objects to having their terms and conditions worsened (which is what's happening here, let's be clear about that, even if what's being proposed is still a pretty good deal) should have the right to strike - my family background is coalminers and dock workers, so I have a history of militancy. I do think, though, that if the union is asking members to strike, they have the duty to put the facts and the arguments clearly, and I'm slightly disappointed that in this case, many of the unions have been concentrating so hard on winning the media war that they've neglected to give members the full picture. I fully understand why they have to do it, but I'd just be happier if they could take the moral high ground a bit, and not sink to the level of the media, if you see what I mean.
FWIW, I don't think anyone here is being greedy and unreasonable. I'm a public sector worker as well. It just boils my piss a bit that people are being misinformed, and underinformed, about a subject that is going to have such a massive effect on their futures. We will already be paying more than we thought for those pensioners, public and private sector, who have already retired on the basis of promises made decades ago, and the costs of which have been miscalculated. We need to have a serious debate about whether our children will be able to afford our pensions, and that debate isn't assisted by either side just pushing their own agenda.
