Completely incorrect. Civil servants have no choice in the matter - pension contributions are deducted from salary.
A contribution towards pensions is deducted from their salary. The majority of the funding for their pension comes from the exchequer. This is a massive cost to the country and is ignored by the unions when they are deciding how the country is run.
I would like to country to be run by the government and I would like managers to be allowed to manage. We all hear about vested interest groups like the building industry lobby and how they are damaging the country. No vested interest group does more to damage the country or further disenfranchise the poorest in our communities than the public sector unions. Their policy of lobbying for wealth redistribution from the poor to the protected parts of the middle classes is the most cynical sell-out of any supposedly socialist group I have ever heard of. They are a cancer in this economy and this society.
