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.

Providence Health & Services in Oregon has asked federal mediators to revisit negotiations with doctors and other advanced clinical providers set to go on strike next week.

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.

Nearly 5,000 nurses, doctors and other health workers at Providence Health & Services hospitals and clinics in Oregon are walking off their jobs beginning 6 a.m. Friday. It is set to be the largest strike by health workers in the state’s history — and the first involving a union representing doctors.
