My wife recently hired a young woman, who in the interview seemed extremely exceptional... she was outgoing, intelligent, had all the right schooling and references... her first week there she came to my wife in a panic that someone had given out her information to a guy who was stalking her online. My wife obviously took this very seriously, and took her to a board room to discuss... the conversation quickly broke down as the female described the situation it seemed obvious (I don't recall the exact details at the moment) that it would have been impossible for this individual to have gained any information about the female, at least from her very very new job.
A week or so later, she came to my wife again, in tears. She claimed that her co-workers were in cahoots against her, talked about her all the time behind her back, made running jokes at her expense, and finally deleted the work she had due. My wife has known her co-workers for years, and obviously found all this a little hard to swallow. Keep in mind she's been at this job for less than three weeks at this point. My wife gets IT to look into the issue, and they discover that the work was never on the computer to begin with. Suddenly the new girl remembers that she had it all on a flash drive, which she must have taken home. Or maybe one of the other employees stole it, trying to sabotage her.
Also, somewhere in this conversation her stalker comes up again, but this time the stalker is a female. Someone from high school, apparently. When my wife mentions the male stalker, the girl begins to cry that nobody ever understands her.
I told my wife: you have to get rid of this chick before she comes in and stabs the fuck out of everyone. And get your supervisor to do the firing. That seems like a lot of warning signs to me. Am I right?
Could be schizophrenia?
When step-Mang #2 got married, I sat next to one of her good friends at the wedding reception. Seemed like a nice, sensitive young woman. But she talked...A LOT. I started to realize that across however many hours dinner lasted, she talked entirely about herself and while I learned a great many things about her extremely complicated, drama-stricken life, she didn't once ask anything about me. I could have written biography of moderate length about her while she, on the other hand, would've had trouble remembering my name.
When she wasn't yammering to me, she kept going over to step-Mang #2 and tried to embroil her in yet more drama, plots and what have you.(Most of which centered around the desperately unhealthy relationship between her on again, off again boyfriend). She was fairly sure that all the woman in the bathroom room were talking about her, giving her the 'evil eye' and all the rest. Aside from the compulsive talking she was drinking at a fairly alarming rate, even for a wedding.
Later on, we heard from Step Mang #2 that this behaviour got worse & worse complete with 'voices in the head' and all that. Turned out to be a classic schizophrenic break which, thankfully was diagnosed and medicated (correctly for once) and the person concerned is doing pretty well and getting on with things.
One of the interesting features of schizophrenia that I heard about is the way in which it slices up time perception & memory. It's possible that she (the new hiree) sincerely believed she had done the work or was about to. Because a person suffering from this loses the normal linear sequence of events, they can frequently end up in odd situations, places etc without a proper memory of the how & why. Maybe she believed she had done the work and couldn't find it because of 'time slippage' and then panicked that it was missing. If you're paranoid, you're going to assume someone else must've fucked with it.
This woman sounds like she needs help. Gotta wonder if this has been diagnosed or whether she's got medication(s) that are not being used correctly, if at all.
Don't know enough about these things in terms of threat level to your wife or other employees. Having seen this in Step Mang 2's friend (and some others) it seems like a different type of problem to the 'I hate my parents/school/police so I'll shoot them' syndrome.
