Hillsdale College's Imprimis ran an op-ed piece by Mark Mix, president of the National Right to Work Legal Defense Foundation. In other words, he is a staunch foe of unionization. The final paragraph sums up what he is driving at:
"Fortunately, there are signs that taxpayers are recognizing the negative consequences of compulsory unionism in the public sector. Just this March, legislatures in Wisconsin and Ohio revoked compulsory powers of government union bosses, and similar efforts are underway in several other states. Furthermore, the NLRB’s blatantly political and un-constitutional power play with regard to Boeing’s South Carolina production line is sure to strike fair-minded Americans as beyond the pale. Now more than ever, it is time to push home the point that all American workers in all 50 states should be granted the full freedom of association—which includes the freedom not to associate—in the area of union membership."
