She seems nice enough, I don't know her personally and I have absolutely nothing against her in general.
But she doesn't knock. She doesn't take no for an answer either. Holding a meeting in the conference room? She'll pop in and start hoovering. Sitting in a room giving a performance review? She'll open the door and begin to dust. She'll also leave the door wide open when she leaves a room - despite there being three companies within this building and our facilities being access controlled (which obviously won't work if the door is left open).
I've asked her to knock a gazillion times. She won't. I've asked her to come back later when she has disturbed important stuff. She'll huff and puff and will need to be asked at least twice before actually stopping whatever it is she's doing. My colleague had a talk, too, about the door being left open for anyone to look right at our whiteboard with confidential calculations for a sale. Nothing seems to work.
And, yes, she does understand. It's not a language issue. She just doesn't seem to be arsed.
I get that this woman is paid a lot less than myself and my colleagues and that she probably has kids or a life to get back to after her shift. I really don't want to get her into trouble. I do desperately want her to be minimally considerate of the people working here, though.
So, AIBU to complain to the building manager?
