Physicians, nurse practitioners and physician assistants at Phoenix-based Banner Health have filed a petition for union representation with the Union of American Physicians and Dentists, the union said in a June 22 news release shared with Becker’s. If the election succeeds, the bargaining unit would include more than 240 clinicians across 31 clinic locations in the Phoenix metropolitan area. The clinicians serve more than 500,000 patients annually, according to the union.
