The US Labor Relations Board has given up regulating Musk's space exploration technology company.

The National Labor Relations Board has dropped the legal action against Elon Musk's space exploration technology company, SpaceX, and dismissed the case accusing the company of firing 8 engineers for writing and distributing a public letter criticizing Musk. The National Labor Relations Board cited a recent opinion by the National Mediation Board, stating that SpaceX's engineers should be under the jurisdiction of the National Mediation Board, not the National Labor Relations Board, and therefore dismissed the case. This dismissal is a victory for SpaceX as employees under the jurisdiction of the National Mediation Board have different protections under federal law, reducing the legal recourse available to current and former SpaceX employees when alleging retaliation.
