I’ve had a similar issue where someone on a different team reported me to her manager over lack of sympathy because she had to wfh during the Christmas season. I had made a noncommittal sound because I was staring at my computer screen working.
Mind, it was April and my male colleague next to me didn’t say anything either and was doing the same as me.
The same woman had told me this in January and I showed sympathy then. Not sure why me not giving full attention upset her but him not.
Cue two more incidents because I avoided her and kept things to writing and ended up reporting her to HR after she chose to tell the office she reported me and didn’t expect the office to think she was childish for doing so. She wasn’t aware of her own reputation of being annoying, vocally loud to the point that others had reported her, calling her a security risk when they were in the phones and they could clearly hear her ( secure office, key fobs needed).
Been in her presence alone twice in 10 months and conversations around others three, so fifth encounter was HR.
Didn’t help I was pregnant at the time and there were concerns. My team lead was no help and neither was her team lead hence me going to HR.
I went on maternity leave and when I came for a visit a month later she was gone.
