Having a problem with any kind of union is kind of silly, specially those of public servants.
It should be the government who ensures that all work has a liveable wage, that is the whole reason why there are minimum wages to begin with. But its up to the employers to pay it up, you should be able to live off the work that you provide, no matter what the work is.
You do not seem to understand what equality of outcome means, it certainly does not mean a living wage. A living wage is nothing more then a wage someone could live off, and yes, this would include some extra spending. This has nothing to do with "equal outcome" but rather with ensuring that the people can live off the fruits of their own labour. People who work should have no need for government assistance, their pay should be enough to cover the cost for everything that they need. Equality off outcome would entail things like "It should not matter if someone collects garbage for a living, they deserve the same pay as that surgeon", and no one is pushing for anything like that.
