I started a job 6 months ago and work with a girl who seems to be a bit off. She always stares very intensely at other people and never says anything. She stands very uncomfortably close to other coworkers, behind them, next to them, etc., and never says anything, just stares and listens. She eavesdrops on other people's conversations and reads over their shoulders on computer screens. She's very socially awkward and we all think she has some type of disability or diagnosis that we don't know about. It's becoming very uncomfortable for all of us. The eavesdropping and invading on people's conversations as well as inviting her self places with some of us, and always standing so close to us it's creepy and very uncomfortable. It gets to the point where she stand so close to co-workers that we literally run into her on a daily basis, bump into her, bump into her while we have food in our hands going on our breaks, step on her, etc. and she doesn't say anything, just stares at us when we run into her. It seems as if she doesn't understand where to draw the line and anything about privacy or giving people space, boundaries, etc. It's become a very serious problem and we all feel very uncomfortable and creeped out. We don't want to say anything to our boss because we're pretty sure she has some kind of diagnosis and don't want to create a problem but the behavior is becoming intolerable and extremely creepy. The work environment has become on edge and uncomfortable while she's at work. Some of us actually have a diagnosed anxiety disorder and we like our space without people staring at us or breathing down our necks and when she's at work, work has become intolerable for some of us. What should myself and others do about this individual? Is there any possible diagnosis for this behavior that we don't know about?
