I don't wish to be too hard on these postal workers as they have immediate concerns-making a living--but this is a victory for the plutocracy. They got exactly what they wanted. They got the UAW to agree to binary pay scales etc in '08, that they have now succeeded in doing the same thing with a very strong public sector union is a very bad sign indeed. A deathknell perhaps.
