All workers, union and non-union, public and private, have their workplace rights up for grabs, AFL-CIO Executive Vice President Tefere Gebre says.

Sometime this month, the U.S. Supreme Court will decide if workers still have a right to a voice in the workplace, he told the American Constitution Society, a coalition of progressive attorneys and jurists, including pro-worker labor lawyers. Gebre did not differentiate between classes or types of workers.

The way Gebre and many union leaders see it, the answer to that question will be no.

According to Politico, Arizona's teachers have rejected Gov. Doug Ducey's plan to eventually boost teacher salaries by 20 percent and will walk out on April 26, union leaders say.

The announcement follows a vote by more than 57,000 school employees in the state, with 78 percent backing a walkout.
