evidence: From installing former union official Marty Walsh as Labor secretary, to outfitting the National Labor Relations Board with union alums, to issuing a spate of union-friendly executive orders, the White House has taken significant steps toward expanding union membership despite the challenges presented by a narrowly divided Congress. [...] At the National Labor Relations Board, Biden lost no time in clearing out employer-aligned Trump appointees — General Counsel Peter Robb and Deputy General Counsel Alice Stock — the first president in more than 70 years to exercise that power. [...] At the same time, Biden has issued a spate of union-friendly executive orders. In April 2021, he signed one creating a task force committed to studying how the federal government could act unilaterally to expand workers’ right to join a union. The group released its recommendations in February; agencies have since published the steps they are taking to comply.
