At the facility in which i work, we often have nurses who come to work after having worked a twelve hour, all night shift at another facility. This is followed by an eight to ten hour day at my place of employment. This means that the nurse has now worked over twenty hours!@!!!! Is this legal? And if not, what can i do? I do not want to be a whistle blower and lose my job, however, i worry for the safety of my patients! Please help and oh, by the way, the DON is aware that they are doing this, so, don't answer with tell the boss!
