Tesla found guilty of silencing workers and violating U.S. labor law.

A U.S. labor board official has ruled that Tesla supervisors at a Florida service center violated U.S. labor law by telling employees not to discuss pay and other working conditions or bring complaints to higher level managers. The judge ordered Tesla to cease and desist from violating workers' rights and to post notice of the violations in the service center and email it to employees. This is the latest loss for Tesla before the labor board as it also faces lawsuits alleging widespread race and sex discrimination at its assembly plants.
