The efforts to unionize more than 3,900 nurses at three Indiana University Health hospitals have stalled. The United Steelworkers union is working to earn support from nurses at IU Health's Methodist, University and Riley hospitals in Indianapolis, where there have been complaints of low staffing levels, low pay and troublesome attendance policies. But Maria Somma, organizing coordinator for the Pittsburgh-based Steelworkers union, which was invited to work on the unionizing effort about nine months ago, said that there's no estimated date for a vote.
