The Ontario Nurses Association says it can't accept a cut in wages and benefits for nurses in their next contract.
They're awaiting the outcome of an arbitration hearing held on the weekend with the Ontario Hospital Association.
President of the Nurse's Association Linda Haslum-Stroud says nurses have already suffered through a two-year wage freeze.
Nurses will see their existing contract expire at the end of this month.
The ONA represents nurses at hospitals in a number of communities across northwestern Ontario including
Kenora, Dryden, Thunder Bay and Fort Frances.
