At PajamasMedia, Peter Ferrara explains why government employees should not be in trade unions:

Government employees … work for democratically elected officials representing the will of the people. This is just one reason why there is no legitimate role for government unions, and there should be no collective bargaining rights for public servants.

Since public servants work for the people, their wages, benefits, and working conditions are set in accordance with the will of the people, as determined by the democratic process. This is why it is not legitimate to ask the people to compromise with public servants in collective bargaining. And this is why the pay, benefits, and working conditions for federal workers are set by acts of Congress, not through collective bargaining.

If public servants do not like the pay, benefits, and working conditions offered to them by the people as determined through the democratic process, nothing requires them to be public servants. …

Since public servants work for the people, any strike by them would be a strike against the people. The government cannot allow the essential public services it provides to be shut down while it negotiates the pay, benefits, and working conditions for public servants through collective bargaining. …

Government unions themselves can choose who negotiates with them on behalf of the people, through their votes and political support. In return for lavish pay and benefits far exceeding private compensation, the unions provide a kickback in campaign contributions and muscle to their political benefactors, financed by the taxpayers. This inherent conflict of interest involved in government unions leads to oppressive political corruption, where there is no political limit as well as no market limit to the plunder of the public by government unions.

He goes on to discuss what is happening in Wisconsin:

What is at stake in Wisconsin is whether public servants work for the American people, or whether the American people work for a “public servant” aristocracy enjoying far greater pay and benefits than the taxpayers who are forced to subsidize them …

What we are witnessing in Wisconsin today is the total breakdown of democracy, and the collapse of the rule of law. The Democrat Party in the state has refused to abide by the results of the election last November, and so has shut down the state legislature. The government unions are breaking the law by going out on strike. The anti-democracy protestors in Madison are breaking the law by continuing to occupy the state capitol. Doctors are breaking the law by writing fraudulent “sick notes.” The remaining Democrat state senators after last fall’s election have fled the state to hide from the law. …

Ferrara approves of the bill that Wisconsin’s Governor Walker is trying to pass. It would, he writes, “greatly benefit state and local workers by terminating government collection and payment of their union dues”, because “this gives power to each worker to voluntarily decide if they want to pay those dues.” And this is a policy, he urges, that “needs to be adopted in every state, as taxpayer money going to government union dues is the root of political corruption in America”.

We ourselves, being theoreticians only, can be far more radical in our prescriptions. We would like to see government unions banned, and the withering away of all others.
