Facebook whistleblower sues company to stop arbitration against her

OAKLAND, Calif. (CN) — A bestselling author sued Meta Thursday, claiming the social media giant enforced unlawful arbitration proceedings against her after she wrote a book about her experiences at Facebook as its director of global public policy.

Sarah Wynn-Williams worked for Facebook from 2011 until her firing in 2017, which she claims was in retaliation for reporting her boss, Facebook vice president for public policy Joel Kaplan, for sexual harassment. Kaplan is currently the chief global affairs officer at Meta Platforms.

In her 2025 bestselling memoir “Careless People: A Cautionary Tale of Power, Greed, and Lost Idealism,” she details her termination along with other revelations about Facebook that she called “lethal carelessness.”

In Wynn-Williams’ complaint filed in the U.S. District Court for the Northern District of California, she says Meta is punishing her for disclosing its “illegal and indefensible workplace conditions and corporate misconduct to federal regulators, to Congress” and in her memoir. She also claims, after her termination, Meta refused to pay back business expenses of approximately $310,000, based on a severance agreement.

“Meta does not and cannot deny the truth,” she says. “Rather than focus on rectifying the issues they raise, Meta has attempted to distract and retaliate, including by launching an unlawful arbitration enforcement action against Ms. Wynn-Williams seeking untold millions of dollars Ms. Wynn-Williams does not have in purported ‘damages.’”

After Meta failed to block “Careless People” from being published, Wynn-Williams says an emergency arbitrator’s broad “interim award” now limits her speech and ability to work and allows Meta to monitor and penalize her actions regardless of their connection to the book.

Some of the experiences Wynn-Williams claims to have witnessed during her tenure at Facebook include the company’s failure to invest in staff and resources, which may have increased tensions in Myanmar, and Facebook founder Mark Zuckerberg’s “readiness to hand the Chinese Communist Party access to the data of millions of Chinese and U.S. citizens as a quid pro quo for entry to the Chinese market.”

Along with her own experience of sexual harassment, she says she saw how young women were exploited and emotionally manipulated through the company’s social media platforms, which included targeting teenage girls with advertisements for beauty products after they deleted selfies.

“At its core, this case is about Meta’s punitive approach to whistleblowers,” Wynn-Williams’ attorney Debra Katz says in a statement. “Meta should not be allowed to use forced arbitration and nondisclosure agreements to silence conscientious employees who risk their careers to speak out about company abuses that affect public health and safety.”

Wynn-Williams asks for the interim award to be vacated and to stop enforcement of the severance agreement she says she agreed to under duress and which violates provisions of the National Labor Relations Act. She also asks to block any further arbitration from Meta and demands a jury trial.

In an email to Courthouse News, Meta spokesperson Andy Stone says, “This former employee is trying to use the legal process to sell books, which an arbitrator already ruled broke the agreement she signed with the company when she accepted a large severance payment years ago.”

Katz says it is likely current and former Meta employees who signed a forced arbitration agreement will watch the legal proceedings to see whether Meta will succeed in using such agreements to “silence and punish whistleblowers.”

“We are hopeful that the court will put a stop to this retaliatory overreach,” she says.
