Ruling just a week after hearing oral arguments in the case, the Wisconsin Supreme Court has overturned a lower-court ruling that had struck down the law. Though other challenges are foreseen, the law reining-in collective bargaining powers for public school employees and other state workers is now likely to go into effect – at least for the time being.

Collective bargaining was always a bad idea for workers employed by a state-run monopoly, because it lacks the checks and balances of the private sector. When UPS went on strike, customers could – and did in great numbers – shift their business to FedEx, DHL and others. But taxpayers must keep paying for the public schools despite their rising costs and collapsing productivity.

Still, it is unlikely that this measure will control public school costs as well as many observers hope. I explain why in a feature story I wrote for the current (June) issue of The American Spectator. It’s on newstands now, and should also be up on the Spectator’s website within the next few days.
