I work at a small hospital with an RN with 20+ years seniority on the floor. From what I've heard, she's been reported and suspended numerous times for showing up intoxicated at work. She consistently leaves the floor for an hour or more at a time, rarely is in her patients rooms, does not give her medications on time or at all, etc. managers like her because she fills in 4 hour holes when they need coverage. This morning she showed up slurring her words, swearing loudly and overall belligerent. I reported it to the nurse supervisor who, along with our manager, came to "assess", FOUR hours later. Both coming to the conclusion she was perfectly fine. I'm being made to feel guilty and am completely discouraged and disheartened by the whole situation. She needs help, and her patients are not safe if she is impaired. Any advice?
