The Senate has voted to confirm all five members of the National Labor Relations Board, the government body that oversees labor complaints. The vote was held after the Senate reached a deal last month to approve President Obama’s nominees in return for preserving the filibuster. The vote to fill the NLRB gives the panel a quorum of five confirmed members for the first time in a decade. The panel has been slowed in recent years by a Republican refusal to confirm new Democratic members, threatening U.S. workers’ main recourse to defend their right to organize and to protect themselves against anti-union activity by employers.
