"In three widely anticipated decisions, the National Labor Relations Board opened the door for some employers to classify more workers as supervisors and exclude them from union representation. The decisions outraged unions, but didn't go as far as business groups had hoped."

"At issue in the cases, which stemmed from union organizing attempts, were U.S. labor-law provisions that state workers who use "independent judgment" in a "nonroutine" manner to assign or direct other employees, should be considered supervisors, even if they don't have employees who report directly to them. Supervisors aren't guaranteed collective-bargaining rights under the law. A broader interpretation could exclude more workers."

"The AFL-CIO and other labor groups blasted the board, saying the decisions opened the door for millions of workers to lose the right to join a union and imperiled the status of other workers who are already union members. Under labor law, the decisions can't be directly appealed, but the labor federation said it will litigate the same issues in other cases pending before the board and push for a legislative fix to the law."
