Elon Musk broke law with threat to Tesla workers’ stock options, court rules

Appeal judges uphold previous ruling, citing implied threat' in CEO's tweet directed at Fremont employees who wanted to join union

A US appeals court has ruled that Elon Musk violated federal labour law by tweeting that employees of Tesla would lose stock options if they joined a union.

The New Orleans-based 5th US circuit court of appeals upheld a decision by the US National Labor Relations Board that said the 2018 tweet amounted to an unlawful threat that could discourage unionising and ordered Musk to delete it.
