Anyone that doesn't want to work in a closed union shop have every right to do so.  I hear Target, Walmart, and McDonald's welcomes anti-union workers.  As for me and my house, I'd support organized labor any day of the week.  If it's constitutional for one to bear arms, why isn't it equally important to constitutionally protect peoples right to earn a fair and equal livable wage with bennies?  Isn't this what tRump is railing against, to make it possible for welfare to work class to earn a fair, livable wage?
