After being charged with illegally firing workers who criticized Elon Musk, SpaceX yesterday sued the National Labor Relations Board (NLRB) in a lawsuit that claims the US labor agency's structure is unconstitutional.

On Wednesday, an NLRB regional director filed a complaint against SpaceX alleging that it illegally fired eight employees who drafted and distributed an open letter about Musk in 2022. If SpaceX doesn't settle the charges, the company is scheduled to face a hearing with an NLRB administrative law judge (ALJ) starting on March 5.
