An arbitrator has prevented the employee from promoting her book and disparaging the company until private arbitration concludes.

An arbitrator has decided in favor of Meta in a case the company brought against Sarah Wynn-Williams, the former Meta employee who wrote a memoir published this week detailing alleged claims of misconduct at the company.

Meta Platforms on Wednesday won an emergency arbitration ruling to temporarily stop promotion of the tell-all book "Careless People" by a former employee, according to a copy of the ruling published by the social media company.
