Nurses at Pioneer Memorial Hospital in Prineville are voting today on whether to continue with the union. The nurses voted to unionize about two years ago, but haven't been able to come to an agreement over a contract. “They are going through the de-certification process from the ONA which is the Oregon Nurses Association. They actually voted that union in and had never had a union before 22 months ago.” Katy Vitcovich, Senior Vice President of Human Resources for St. Charles, which operates the Prineville Hospital, says nurses will vote in two secret ballot sessions today and tomorrow. We hope to have the results of the vote Thursday.
