The largest U.S. nurses union is planning a day of action in mid-November to protest the lack of federally enforced safety precautions against Ebola. National Nurses United (NNU) announced it will hold events in at least 13 states and the District of Columbia to call attention to the issue. The group has been one of the most vocal critics of the federal response to Ebola, arguing the best way to prepare for a pandemic would be to impose new training and protection requirements for healthcare workers.
