Thats the typical union line of "we should get everyone up to the top, not bash everyone to the bottom".
I could easily introduce a pension scheme in my own company to match that of teachers or doctors. I could do it on Monday.Everyone would join it (and be nuts if they didn't).
I also know that after the first round of retirements, my company would be bankrupt.
Its not bashing the public sector just because they have better pensions. Is bashing them because they, or at least the unions can't see that if they don't change the schemes, the whole thong will fall like a house of cards. And they hold the country to ransom to retain schemes which are mathematically impossible to sustain.
Just as a matter of interest, I'm not in a union. I can only speak from personal experience, but where I work very few people support strikes - I'd say about 1 in 5. And I would dispute the notion of the country being "held to ransom". I think most people strike to show they disagree with something, but how often do strikes change anything? Very rarely.
