Amendment 7 on Alabama's ballot looks like a simple measure to preserve the right to a secret ballot. In reality, it injects voters into a battle between labor and management. The ballot measure provides that Alabama citizens have a fundamental right to vote for public office and employee representation by secret ballot. If passed, it would prohibit unions from organizing by card check, where they get more than half of the employees at a company to check a box on a card saying they want union representation. The sponsor, Republican Rep. Kurt Wallace of Maplesville, said he wants to stop union organizers from harassing employees who won't sign a card. The president of the Alabama AFL-CIO, Al Henley, says it violates federal law and will be challenged in court. Copyright 2012 The Associated Press.
