Workers are seeing these organizations for what they really are: anti-labor institutions that are “unions” in name only, and that are run by unaccountable and affluent upper-middle class bureaucrats—pulling down six-figure salaries—who have nothing but contempt for the workers they represent. These “unions” function not as defensive organizations of the working class, but as direct and enthusiastic accomplices of the corporations in the exploitation of the working class.
