The largest health care strike in Oregon history began early Friday at Providence across the state, as roughly 5,000 frontline health professionals walked off the job. The strike — which includes mostly nurses and 150 doctors and advanced practitioners in addition to thousands of nurses — spans Providence’s eight hospitals in the state.

Area hospitals including Oregon Health & Science University have been planning how to handle transfers during the strike, according to Sara Hottman, a university spokesperson. OHSU is home to the Oregon Medical Coordination Center and is also tabbed by the state to help coordinate during surges in hospital bed demand.

Thousands of health care workers at Providence hospitals and clinics in Oregon are planning to go on strike Jan. 10.

With concern growing over hospital care as a Friday strike looms at Providence Hospitals, representatives from the Oregon Nurses Association will hold a press conference to update the public on their preparations.

Oregon’s Providence hospitals and nearly 5,000 of its workers have yet to agree on terms to bump wages and address staffing shortages. That means the largest health care strike in the state’s history will begin Friday morning.

Roughly 5,000 nurses, hospitalists and other frontline health workers at Providence hospitals and clinics across Oregon are set to go on an open-ended strike starting Jan. 10.

Thousands of nurses are expected to walk out along with dozens of doctors, all members of the Oregon Nurses Association.
