As an H1-B visa holder in a right to work state, my presence here is dictated by either the benevolence of my employer or by my own duplicitousness when I carefully conceal my interviews with other firms.
I think you mean "at-will employment"[1]. "right to work"[2] states limit the ability of union shops to exclude non-union workers. There really needs to be better terminology because people constantly confuse the two.
They're both propaganda labels anyway. If the words had more of a direct relationship to what they were describing, they could never be passed.
People do want the right to work, and also want to have employment at will. They are generally patriots, wish communication was more decent, and would love to be allowed to trade freely.
I don't know. I think popular opinion is against having closed shops, though perhaps not uniformly.
And at first blush, people might react negatively to at-will employment states, but the devil is in the details on proposals to replace at-will employment.
