I am not going to hold my breath but imagine if this really is a possibly, how much things could change.

Union supporters had reason to cheer earlier this month when Wisconsin Gov. Scott Walker’s hated “right to work” law was overturned by a Dane County Circuit Judge. Unfortunately, the decision is all but certain to be overturned by Wisconsin’s conservative Supreme Court. But contained in the case is a line of questioning over the constitutionality of the right-to-work concept that has quietly been playing out in federal courts.

The result could be that all right-to-work laws are nullified—and sooner than you might imagine.
“This is a law,” says Marquette Law Professor Paul Secunda, “that compels one private party to provide benefits to another private party with no compensation.” He is convinced that right-to-work laws, which permit represented workers to quit their union and stop paying fees while simultaneously obligating that union to continue to spend resources representing them, are an unconstitutional “taking.”

If the issue makes its way up to the Supreme Court, and the justices agree with Secunda, the result could overturn the section of the National Labor Relations Act that allows states to pass right-to-work measures as well as the statutes in all 26 states that have passed them in one fell swoop.
