The National Labor Relations Board has upheld unions’ right to display large, inflatable rats at workplaces of secondary employers, including companies that hire nonunion firms to build or retrofit buildings.
In a May 26 decision, NLRB’s three Democrats—Chairman Wilma Liebman and members Craig Becker and Mark Pearce—said the use of rats at such workplaces is not coercive. They said unions protesting at a hospital did not shout, block access or otherwise disrupt hospital operations.
