I've worked with this woman for a few years now and she is a really friendly and chatty person. I got along with her quite well at first but it seems that her demeanour is partly to cover up the fact she is completely unable to do her job.
It's been reported time after time and it ends up with her weeping at her desk 'why does nobody like me' which leaves managers to scared to do anything about it because although there's hard evidence she is not doing her job, they are scared of her going down a legal route and saying we have a bullying culture.
She obtained my phone number with some excuse when she first started and although I try and avoid her at work (her incompetence makes my life very difficult) she will text me in the evenings and weekends telling me to have a lovely night/weekend. I don't even open the messages anymore. I don't speak to her directly about my life but she obtains information from other people I do chat to and will tell me 'enjoy your dinner at name of restaurant tonight!'. She has friend requested me on three forms of social media and I have declined all of them.
I'm finding myself becoming more and more hostile because of the impact she's having on my work. She needs to process some paperwork before I can deal with my stage of it and she has been hiding the paperwork on her desk and denying all knowledge of having it which has a knock on effect and is causing chaos and means I have to stay late most days to clear up her mess. She's in her early 40's but acts a lot younger and if challenged about something she hasn't done she starts crying.
Others in the office aren't having to work with her directly so are just aware of her cheery personality and optimistic outlook (think Pollyanna x 10000). She's told everyone else in the office that she WILL wear me down and win my friendship eventually.
AIBU to speak to another adult and explain that we can be civil at work but I don't want to be her friend and would prefer she not contact me outside of working hours? It would undoubtedly end in tears.
