Three Amazon software engineers say their employer is retaliating against them for publicly backing limits on data centers, and they've taken their complaint to Seattle's government.

According to The Verge, the engineers testified earlier this month at Seattle City Council hearings about data centers. They opened their testimony by pointing to a city law that bars employers from discriminating against workers over political speech. Now, The Verge reports, they're accusing Amazon of breaking that same law by disciplining them for what they said.

Wired reports that the three workers have filed a complaint with Seattle's civil rights office, accusing Amazon of illegally retaliating against them for expressing their personal views. The engineers say they are under internal investigation, and according to The Verge, they say they are facing termination for supporting data center limits at the hearings, which touched on a proposed moratorium.

The dispute sits at the intersection of two fast-growing tensions. Data centers — the warehouses of computers that power cloud services and artificial intelligence — consume large amounts of energy and water, and cities are increasingly debating whether to cap their growth. At the same time, tech companies and their employees have repeatedly clashed over how much workers can say in public about their employers' business.

The core legal question is whether the engineers' testimony counts as protected political speech under Seattle law, or whether Amazon can treat it as a workplace matter. The outcome could shape how freely tech workers can weigh in on local policy fights that involve their own employers.

Why it matters: As AI drives a building boom in data centers, this case tests whether the employees closest to that infrastructure can publicly question it without losing their jobs.
