Cincinnati Enquirer columnist Peter Bronson notes (h/t ShopFloor) that in a Pennsylvania organizing campaign, the UNITE HERE union invaded workers' privacy "by illegally using license plates to track them down... just a taste of what non-union workers will face if the Senate passes 'card check'". In many cases the unions obtained identities of the workers' family members and friends as well. The campaign included uninvited appearances at the homes of Cintas employees. Earlier this month the U.S. Supreme Court declined to disturb a verdict against the union over the tactics.
