The National Labor Relations Board’s new election rules go into effect April 14, and Deputy General Counsel Jennifer Abruzzo announced ($) that training on those rules for regional office employees will begin in Washington on March 16. The NLRB’s regional offices will also offer educational meetings to labor law practitioners March 23 through April 13. The election rule changes take effect April 14.

Meanwhile, litigation challenging the rule change remains pending in two federal district courts. The U.S. Chamber of Commerce and National Association of Manufacturers (NAM) lead a lawsuit filed by business groups in the District of Columbia. On February 5, the plaintiffs filed a motion for summary judgment. A separate lawsuit brought by the National Federation of Independent Business (NFIB) and Associated Buildters and Contractors (ABC) is pending in the Western District of Texas.

The rule is also under attack in Congress as the Senate voted 53-46 on March 4 to overturn the new election rules. The legislation will now go to the House, which is also expected to pass it. President Obama has said he will veto the measure.
