So I work with a coworker who is rude beyond belief. Not a nurse, but clinical staff. I have gotten into my job and enjoy what I do, despite the stress, and I get along fine with everyone else, but this coworker has a problem with everyone. I have been told stories about arguments, defiance, and issues with this coworker by almost all of my other coworkers. I don't know the coworker much because I honestly just try to stay away from them after they have have been rude to me a few times. Any time I talk to the coworker, even something polite like "good morning", or "how are you" or even ask a question like "do you have any such and such supplies over here", the coworker is just rude and cold. I have had other coworkers come to me to complain about this person, saying how rude and lazy and unhelpful they are, and I have seen it as well. Breaking rules, slacking on work, and being nasty to other coworkers and even patients. I don't gossip about the coworker but I did talk to the manager about them and then, the coworker confronted me, screaming and threatening me in front of coworkers and patients. I am fed up with this bully, and with working hard while they do hardly anything, and listening to everyone complain about them. Everyone says, "oh that's just how they are, we think that they're unhappy so they take it out on everyone else." I even had a coworker struggling one day to manage her patients and she broke down crying, meanwhile, what did rude coworker do? Go off and socialize in another area, not even offering to help! I don't understand the mentality of this coworker, I would always try to help someone if I see they were struggling like that. It's called being a decent person. Whenever I am not struggling under my workload (which isn't a lot since I am always slammed doing everything because this coworker does nothing...) I go out to the other areas and offer my help to other coworkers, who are all polite and helpful to me as well, and who I am not afraid to ask questions or say good morning to... The coworker has the worst attitude I've ever seen in a fellow employee and I'm not sure what to do. Any advice or similar experiences? What can I do?
