On March 9, 2021, the United States House of Representatives passed the Protecting the Right to Organize (PRO) Act. The PRO Act (the Act), if it becomes law, would make vast, union-friendly changes to the National Labor Relations Act (NLRA). The House originally passed the Act in 2019, but it did not make any progress in the Senate. This time, its fate may depend on whether the Senate eliminates the filibuster. Even if the Act doesn’t get through the Senate in its entirety, it may be possible for parts of the Act to pass the Senate and reach President Biden, who has already spoken emphatically about his support for unions and union organizing.
