Summary Points
- Workers’ data is a growing AI commodity: Emails, messages, and work files are being sold to train AI, often with few privacy protections for employees.
- Spirit’s records raised major concerns: A proposed Google deal covered billions of emails and chat messages, plus employee travel and training data.
- A new safeguard is proposed: An independent firm will remove identifying details and check that records can’t be linked back to individuals; sensitive medical, investigation, labor, and safety files are excluded.
- The deal could set a precedent—but isn’t final: Google may walk away if more than 8% of the data is removed, and a judge still needs to approve the agreement.
A Union Pushes Back on a Data Sale
Spirit Airlines’ records could soon help Google improve its AI tools. The proposed $10 million sale covers decades of company data, including billions of emails and hundreds of millions of Microsoft Teams messages.
The Association of Flight Attendants argued that Google’s initial privacy safeguards did not do enough to protect workers. The union negotiated a revised agreement that requires Spirit to hire Tonic AI to remove information that could identify employees or customers.
Privacy Protections, With Limits
Tonic must also check that people cannot link the cleaned data back to specific individuals. Google has agreed to keep the data in that de-identified form. The deal excludes medical records, investigation files, labor-relations documents and some aviation safety information.
The agreement does not give each flight attendant a personal opt-out. Instead, it lets Google abandon the purchase if the cleaning process removes more than 8% of the data. A judge still must approve the deal.
A Test for Worker Data Rights
The case highlights a growing gap: Privacy laws often protect consumers but offer fewer safeguards for workers whose emails and work records may feed AI systems. Airlines also warn that mishandling safety reports could discourage employees from speaking up.
De-identification may help companies use records while reducing privacy risks. Still, workers and unions will want clear limits, oversight and accountability. This agreement could offer a model, but its protections will face a real test if the sale goes ahead.
