That's exactly what happened to me as a new nurse in L and D 8 years ago with my orienting nurse: she belittled me for not knowing how to do certain things or asking "stupid" questions, and she never gave me constructive criticism or really helped me learn- she would actually sit at the nurse's station while I worked and stumbled along. She went behind my back and talked about how incompetent I was and how they shouldn't have hired me in the first place. She thrived on my insecurity. My confidence tanked, and I would come home every night in tears, pouring my heart out to my wonderful husband, my rock. I finally confronted her when I couldn't take it anymore. I took her into an empty patient's room and told her how hurtful her comments were. Her response? Basically: I really don't care about you as a person, you need to get it together and I can't believe you don't know how to do basic things. I blew up at her, telling her off. She stormed away, never bothering me again. Although management knew what was going on, nothing was ever done. But the damage was done to me emotionally and professionally, thanks to her. I still fight my insecurities. I'm not there anymore, but have seen this same behavior occur in my other job now, although in a more subtle way. It's sad.
