The plaintiffs had asked Orrick for a temporary restraining order blocking Meta from completing its layoffs while they pursue their claims in private arbitration.
Their motion for a preliminary injunction, a longer-lasting temporary order, is pending. Orrick on Friday suggested that he could change his mind once he has more information about the layoffs.
Lawyers for the plaintiffs said during a hearing on Thursday that along with their jobs and salaries, the workers stood to lose valuable stock options and their health insurance, imperiling their medical care for pregnancies and other conditions.
"There's no do-over for bonding with a new baby or giving birth or having active medical treatment," one of the lawyers, Barbara Cowan, told Orrick.
Erin Connell, who represents Meta, countered that the workers were losing only employer-subsidized insurance, and not their coverage altogether. Those are the typical kinds of damages that can be recouped later on if the plaintiffs win their cases in arbitration, Connell said.
The workers say Meta's agreements require employees to arbitrate workplace disputes individually, but do not apply to requests for temporary relief.
Most workers at large companies sign arbitration agreements, which generally require employees to pursue workplace claims individually rather than through class actions in court. Companies say arbitration can provide a faster, cheaper alternative to litigation, while critics say it often favors employers and discourages workers from bringing claims.
Exceptions in arbitration agreements for temporary relief are common, but they are typically invoked in cases involving the alleged theft of trade secrets or the solicitation of clients or employees, and not layoffs of at-will employees.
The plaintiffs, who filed the lawsuit anonymously, include engineers, managers, researchers and designers. They were notified in May of the layoffs, which are scheduled to be finalized on July 22 for many workers and later in July or August for others, according to court filings.
Laid-off workers remain on the payroll but lost access to Meta systems on May 20 and have not performed work for the company since, Meta said in court filings.
They claim that Meta used a number of internal AI-assisted systems to score and rank employees on a termination list. Those included a large language model assistant known as "Metamate," an employee-trained "second brain" that tracked workers' communications and documents, and a productivity score drawn from scanning keystrokes, screen content, emails and browser history, according to the lawsuit.
Meta did not pause these systems while employees were on vacations and legally protected leave periods, and their AI adoption scores used as inputs for layoff selection dropped as a result, the plaintiffs said.
