Tesla Labor Practices and Musk Tweet Broke the Law, Judge Rules

Tesla Inc. committed a series of violations of the National Labor Relations Act in 2017 and last year, a judge ruled Friday.

The electric-car maker illegally threatened and retaliated against employees, according to Amita Baman Tracy, an administrative law judge in California. A tweet that Elon Musk sent in May 2018, which suggested employees who chose to join a union would give up company-paid stock options, was among the incidents the judge ruled were in violation of the law.
