I am somewhat against striking, I am umming and urring about the principle for which they are striking but striking is not the way to resolve anything. It hurts private sector workers directly in various forms. Although you get the 'standing up for your rights' argument if you flipped it and took an extreme example of the private sector striking and the government then saying to the public sector to cough up time and money to cover the strike by the private sector then I am sure the whole ethos from them about standing up for this and that would be straight out the window.
As for pensions, my own view, anyone with any sense knows pensions are defunkt, the days of a government looking after people in old age has long since gone, and I am not sure if anyone had noticed it but the country is flat broke, I am not sure where this money is meant to magically appear from? Maybe we just borrow it...
