Artificial intelligence use at center of 1-day strike by Kaiser mental health care workers

Roughly 2,400 Northern California Kaiser Permanente mental health workers, represented by the National Union of Healthcare Workers, staged a one-day strike over the health system's use of AI in patient communications, triage and note-taking. The workers, bargaining under an expired contract since September 2025, were joined by a 23,000-member sympathy strike from the California Nurses Association.
