The National Labor Relations Board assault on state Right to Work laws is under assault itself.

 The Post and Courier of South Carolina opines that the attack could doom big labor. Here's why: Organized labor's political supporters took a beating in last year's elections at every level throughout the nation. Now the unions are fighting back -- and the "right to work" states of the South and West are rhetorical and actual targets, especially South Carolina. Consider the latest threat by the National Labor Relations Board.  Acting General Council Lafe Solomon wrote attorneys general in South Carolina, South Dakota, Arizona and Utah on April 22 that constitutional amendments requiring a secret ballot for union elections adopted by voters in all four states last year are a violation of federal law, and that he plans to sue them in federal courts to invalidate the state laws. The constitutional amendment requiring that the decision to form a union must be reached through secret ballot was approved by 86 percent of South Carolina voters last November. Voter approval rates were 79 percent in South Dakota, 61 percent in Arizona and 60 percent in Utah. The Solomon threat comes on top of a complaint by the NLRB against Boeing for opening a production line for the 787 Dreamliner in North Charleston, claiming that it was illegal retaliation against unionized workers in Washington state.
