I was in an incident with an unwitnessed fall and my charge nurse denied me to do my job responsibilities and informed me to say I never was aware of the fall. When asked by supervisors I denied it as was told, and than stated that I was aware of it. I am currently suspended from work, until grievance meeting. My work threatened me with either quitting or they will fire me and turn my license into the state. Are they aloud to threaten me like this?
