Washington, DC's largest private hospital has fired 11 nurses and five support staff members who failed to make it to work during the back-to-back snowstorms that paralyzed the region in February. Dozens of staff members at Washington Hospital Center face internal investigations, union representatives say, and it is unclear how many employees will lose their jobs. The nurses union, Nurses United of the National Capital Region, has filed a class-action grievance with the hospital, the Washington Post reports.
