if the government had any balls they would end final salary pensions for public sector workers (like most companies have had to because they are simply unaffordable).
if I was Georgie I'd lop a bit more off the pension deal each time they go on strike, and then, when they have finally succumbed, lop off a bit more for good measure to teach them a lesson - if they don't like it then they can go compete with everyone else in the private sector.
