In labor news, the Republican-controlled National Labor Relations Board has issued a new ruling that could block millions of workers from joining a union. The board broadened its definition of who can be considered a supervisor. Under federal law, employees defined as supervisors aren’t entitled to legal protections ensuring their right to join unions. AFL-CIO President John Sweeney said the board’s decision would immediately deny as many as 8 million workers their basic right to have a voice on the job.
