Review & Outlook: Michigan Union Tell-All - WSJ.com: " . . . The pattern in new right-to-work states is that union membership plunges when it is voluntary. That's what happened in Wisconsin and Indiana, and it will probably happen in Michigan too. Yet the most revealing news in the Cook memo is how little the union discusses assisting workers so more will voluntarily join unions. Instead the focus is how to continue coercing workers to keep paying dues. No wonder that the percentage of government workers who belong to unions fell last year. The Cook memo is damning proof that the main goal of union leaders is to enhance the power of union leaders, not of workers. . . ."
That's the problem with unions in the US--the priority is keeping the union leaders in power.
