Wilma B. Liebman (born 1950) is an American lawyer and civil servant who is best known for serving as a member of the National Labor Relations Board (NLRB).

[2][4] Immediately upon graduation from law school she was appointed a staff attorney with the National Labor Relations Board, and served with the agency until 1980.

[7] In 1994, she was appointed to a three-person panel by the National Mediation Board, and helped resolve the 1994–95 Major League Baseball strike in the U.S. and Canada.

President Bill Clinton appointed Liebman as a member of the NLRB in October 1997, and the United States Senate confirmed her on November 14.

[16] She clashed repeatedly with Battista during a hearing before the House Committee on Education and Labor in December 2007, declaring "Virtually every recent policy choice by the board impedes collective bargaining, creates obstacles to union representation or favors employer interests.

[22][23][24] Just before the board lost a quorum, the five members agreed to delegate their authority to a three-person panel (as provided for by the National Labor Relations Act).

[24][25] Liebman and Schaumber informally agreed to decide only those cases which were noncontroversial (in their view), and issued more than 400 decisions between January 2008 and September 2009.

[22][23][26][27] In September 2009, the Justice Department asked the U.S. Supreme Court to immediately hear arguments concerning the dispute, given the high stakes involved.

"It is unrealistic to expect fundamental change in labor because we are constrained by the law's statutory text, precedent, the review process and constant turnover of board members," she told a Congressional hearing in September 2009.

[33] Following her resignation from the NLRB, she became a visiting assistant professor in the School of Labor and Employment Relations at the University of Illinois at Urbana-Champaign.
