Nurses at Providence's eight Oregon hospitals approved new contracts on Monday after over six weeks of strike, ending what the state nurses union has described as the largest health care strike in state history.

The agreements call for wage increases ranging from 20% to 42% over the life of the contract, with an immediate 16% to 22% raise upon ratification. It also aligns expiration dates at all the hospitals an augments the factors that go into staffing levels to take patient acuity into account.

The strike, which is one of the largest health care worker labor actions in state history, included thousands of nurses at all eight Providence hospitals in the state.

Providence Health & Services and the union representing nearly 5,000 of its nurses have reached a tentative agreement amid a weeks-long strike.

Nurses on strike at all eight Providence hospitals in Oregon approved new labor contracts in a vote tallied Monday, clearing the way for their return to work. The result means that most striking nurses will return to Providence’s hospitals Thursday.

The Oregon Nurses Association (ONA) reached a tentative agreement with Providence Health following a strike, promising better wages and benefits.

The union representing nearly 5,000 Providence nurses who have been on strike for six weeks has reached a tentative contract deal, for a second time.

Oregon nurses have been on strike since Jan. 10. Some say they’ll vote no, again, on the latest contract proposal.
