Roughly 5,000 nurses, hospitalists and other frontline health workers at Providence hospitals and clinics throughout Oregon are set to go on an open-ended strike starting Jan. 10. The strike could hobble Oregon’s largest health care system and significantly impact health care services across the region as patients seek care elsewhere.

Oregon healthcare workers set to strike after failing negotiations with Providence over staffing and safety concerns.

Healthcare workers represented by the Oregon Nurses Association (ONA) across the state issued a 10-day intent to strike notice to Providence management Monday. The notice comes after a week of bargaining with the hospital system followed by a five-day cooling off period along with additional mediated discussions.
