No its not. There are countless greedy unions out their who have won themselves unreasonable pay and benefits. Just have a look at the drivers on the London Underground, all they do all day is push a lever forward to accelerate and push it back to deccelerate -
they are compensated £46,000+/annum that is more then teachers and nurses earn in the UK. The only reason why they have such generous salaries is because striking would literally paralyse London, people wouldn't be able to get to work etc, so the only choice is to meet their demands. I think they are also wrangling for a £800+ bonus for the Olympics for doing the same work...
Also these are public servants, so effectively they are striking against the general public!
