The Maine Medical Center nurses’ union announced Thursday that it had ratified a new contract that includes 21% in raises over three years.

The contract runs from Jan. 1, 2026, to Dec. 31, 2028, for nurses at the hospital in Portland.

“We’re thrilled to have won so many improvements that will benefit our patients, our community and the 2,500 nurses that work in our hospital,” Meg Sinclair, a Maine Medical Center emergency department nurse and member of the Maine State Nurses Association bargaining team, said in a statement Thursday.

Caroline Cornish, Maine Medical Center spokesperson, said in a statement Thursday that hospital officials are “pleased that our nurses have ratified a new three-year contract. We value the dedication and expertise our nurses bring to patient care every day, and this agreement reflects our shared commitment to providing the highest quality care to our patients and community.”

In addition to raises, the union said the contract includes more workplace violence protections, staffing improvements and increased nurse representation on the hospital’s diversity, equity and inclusion committee.

Maine Med nurses formed a union in 2021 and negotiated the first contract in 2022. They had 15% raises under that contract, which expired last month.
