Destroying unions or trying to hardly seems the best way to going about gaining their support, and just seems would cause unions to dump more money into left wing campaigns.
I have 2 aunts in the teachers unions and they are thoroughly corrupt, and stagnate any meaningful reform in education most of the time, more money more money and more money, both my aunts will make more money retired than they make while working.
I have worked at places where union was trying to get in, one woman in my department filed a restraining order against them for harassing her outside work.
I mean i would love to support unions, the whole better pay better benefits workers rights thing sounds great but how they go about stuff just sits with me wrong. Nevermind that government employees already have benefits and pensions, why do they need collective bargaining? Collective bargaining just says if you do not give us what we want we can shut you down, that is way too much power for state and federal employees to have, especially when it is our tax dollars paying for their salaries, benefits etc, not a private corporation, state workers and federal should get what they get a decent and fair wage and decent and fair benefits but stop trying to leverage our tax dollars into more for you.
