Former National Labor Relations Board (NLRB) member Mark Gaston Pearce saw his five-year term, initiated by former President Obama, come to an end in August 2018. He served as chairman of the NLRB from August 27, 2011, to January 22, 2017.

Last year, President Trump nominated Pearce to serve another term, but his nomination had not yet passed the Senate. Now, according to news reports, Pearce has stated he is walking away and will no longer seek to serve another term at the NLRB.

Pearce served on the board from 2010 through 2018 and oversaw many controversial decisions. From the “ambush election rule” change to crackdowns on employer personnel policies to attacks on class action waivers, Pearce changed the American labor law landscape (although, the current NLRB already has started to undo many of his former rulings).

Stay tuned to see who his successor may be. The board will be operating with only four (instead of the usual five) members until someone else is nominated and confirmed by the Senate.
