I am so frustrated with a co-worker. This nurse calls myself and other co-workers after work hours and on weekends to vent about work. When she calls, it is VERY obvious that she has been drinking alcohol, or taking some other mind-altering substance. She slurs her words and repeats herself over and over. I have never actually witnessed her being impaired at work, but she does have "day old" alcohol on her breath and wears enough perfume to gag a maggot. One night when she WAS on call the answering service was unable to get ahold of her. Then her phone accidentally called a co-worker and there was a recording on her voice mail of a conversation sounding like she was impaired. This was basically swept under the rug by management. Who knows how many other nights she has been like this and no-one knew about it. What do I do? I know she needs help but obviously unless I have proof I cannot report her to the nursing board. Even if she is not actually "drinking" at work.....if you are hungover it affects your work? What to do?
