many of these people are taking care of family members or even friends. these people are lossing money out of their SS and or welfare checks to pay union dues. most of these people dont' see any wages from this but are forced to join the union to provide care for their own family.
so yea the union was shaking down private citizens and taking money from people that needed it the most.
So if you went to take care of your eldery mother because she needed it you would be forced to join the union pay union dues from her check and receive nothing in return.
