A group of 26 Meta employees has sued the company.

They say Meta used AI systems to choose people for layoffs.

The system chose more workers on medical, parental, or family leave.

The lawsuit is in federal court in Oakland, California.

It says Meta used internal AI tools, keystroke checks, and computer rankings to decide who to lay off.

The workers say employees on leave could not get the same scores as active workers.

Meta did not think about leave when it used these scores, the lawsuit says.

Many of the 26 workers took pregnancy or parental leave.

Others took medical leave for disabilities.

One worker said a manager told him that taking approved leave would lead to layoff selection.

About half of the workers took leave for caregiving or pregnancy reasons.

Meta said the claims have no merit.

It said people, not AI, made the decisions.

The lawsuit says Meta broke several federal laws.

These include the Family and Medical Leave Act and the Americans with Disabilities Act.

It also uses "disparate impact," a legal idea the Trump administration has started to stop using.

The workers' lawyers said they want to keep the workers in their jobs until arbitration.

They say the layoffs would cause harm that cannot be fixed.
