Tesla must make CEO Elon Musk delete an "unlawful" tweet about unions posted May 2018, the National Labor Relations Board (NLRB) has ruled.

A legal order was published by the agency on Thursday as part of a long-running case about the collective organizing of employees, and was filed following Tesla's appeal of a 2019 ruling that alleged the company and Musk had violated labor laws.
