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. Macmillan Publishers and its imprint that published the memoir, Flatiron Books, were also named as respondents.

Macmillan and Flatiron Books, the imprint behind Careless People, were named in Meta’s arbitration request. But the publisher claimed that it should not have been pulled in the dispute since it was not party to Wynn-William’s employment contract.
