A novel lawsuit claiming that Meta Platforms relied on discriminatory AI tools to select employees for layoffs highlights the problems workers face in suing employers over the new technology, including proving how it was actually used. The case helps illustrate why a widely predicted wave of employment lawsuits over AI use has yet ‌to arrive. Legal experts say workers often have little understanding of how AI systems are used in the workplace and many have also signed away their right to sue in court, ‌agreeing instead to resolve workplace disputes through a private process called arbitration that can keep such claims from ever being tested publicly.
