Meta’s AI-fueled layoffs of 8,000 employees targeted workers with disabilities and those who took protected medical or family leaves, alleged a lawsuit filed by 26 employees who were selected for termination. Meta used internal AI tools to select employees for layoffs, according to the complaint filed yesterday by 26 “Doe” plaintiffs in US District Court for the Northern District of California.

“Meta did not assemble the termination list through the considered judgment of managers who knew the work. Instead, Meta used a constellation of internal artificial-intelligence systems—including a system referred to internally as ‘Metamate,’ employee-trained ‘second-brain’ agents, keystroke- and activity-monitoring data, AI-token-usage dashboards, and algorithmically assisted performance ranking and calibration—to score, rank, and select employees for inclusion on the list,” the lawsuit said.

Employees were allegedly graded, among other things, on how much they used Meta’s AI tools. “Meta’s internal dashboards classified employees by their stage of adoption of its artificial-intelligence tools, using categories such as ‘AI Native,’ ‘AI First,’ and ‘AI Enabled,’” the lawsuit said.

The lawsuit is apparently “the first against a major US company to challenge the alleged use of AI in conducting layoffs,” according to Reuters. The complaint alleges that Meta’s tools for monitoring employees did not account for differences caused by disabilities and protected leaves.

“Those tools draw on inputs—performance ratings, calibration scores, productivity and output metrics, ‘AI-native’ ratings, and AI-token consumption—that, by design, cannot be accumulated by an employee who is on protected medical or family leave, or whose output is reduced by a disability,” the lawsuit said.

Meta says people, not AI, made layoff decisions

Meta says that people made the layoff decisions. “These claims lack merit and are not based on facts. Workforce management and organizational decisions were and are made by people, not AI,” Meta said in a statement provided to Ars today. Meta did not provide any other comment on the lawsuit.
