Workplace violence among nurses, why are we still discussing this? Literature review

Workplace violence is not new to nursing, or has it changed from generation to generation. We are still seeing intolerable situations in nursing and in most cases; we have not made changes to our organizations to eliminate our tolerance to workplace violence. It used to be called “nurses who eat their young” now we call it “horizontal workplace violence” or just “bullying”. Why is this serious condition still occurring and decreasing our moral on units and even reducing our workforces?
