@Yellowdove, wouldn't it be funny if you found out YOUR AUNT is the one who is lying or if you found out YOUR AUNT has the wrong person and you two gossip-Bettys have been confusing this woman with someone else? You have no idea how this situation could backfire on YOU! Something seems fishy about how you even connected that your aunt and this woman know each other! If this woman didn't tell you, which clearly she didn't, then what were YOU doing to find this out? Maybe you need to report yourself to HR because you don't have enough to do and you are too into someone else's business! Tell HR you need to be written up because you don't know how to tend to your own life! If your aunt is, in fact, working with this woman, then please go to the woman and tell her your aunt is running her mouth so she can fire your aunt PROMPTLY! There is nothing worse than someone who has diarrhea of the mouth, as your aunt has been shown to clearly have! Stop investing time in your coworker's personal life & start investing more time in analyzing why she matters so much to you!
Stalker. You do not know if she has children outside of the home or if she has an open, side, or poly style relationship.. And you have no right to dictate the parameters of her conversations at work. Let this woman do her job, and stop thinking like you have to police the office, Ninny Drew.
Some of the posts hereexcitedly throwing personal insults around like "Ninny Drew," "Stalker," writing in ALL CAPSseem a bit unhinged. I'm struck by the number of people who seem almost desperate to defend someone who lies constantly.
It's like the OP is supposed to be a cardboard cutup saint who never even peeks at someone's social media (er, if a social media user wants their social media to be private, why are they posting stuff publicly?) or even harbor suspicions about someone. Meanwhile, the lady in question is lying her arse off, and we're supposed to give her the benefit of the doubt.
I'd love to start a AIBU where I told the Mumsnet public that horrid people at work are being mean to me just because I enjoy telling lies for no reason and got found out. I suspect the response would be pretty different.
OP, keep your distance from this person and do what you can to limit personal exposure, while making sure you keep an careful eye on her in a discreet manner and document the lies carefully (what she said, what the lie was, who was present at the time, oral/email etc.).
She will lie about something work related sooner or later.
I mean, I doubt she's the next Dorothea Puente or whatever, but she might be caught with her hand in the till at some point, or something similar. My own experience is that people who constantly lie about their personal lives will slip up at work sooner or later.
