I work in an office with 5 people, all women. On the day in question, I was in the office with one of the women. Another colleague came in and excitedly talked about how her and were husband were going to try for a baby. This was particularly good news for her as she had some serious gynaecological problems in her early twenties and she was told she may never be able to have children. She had just been given the all clear. We spent some time talking about children. The woman who I share an office with stayed silent, didn't turn around from her PC and then just walked away and didn't come back until the colleague had gone. I didn't think too much of it.
Later my line manager called me to a meeting and said the woman in my office had made a complaint against me because I had been chatting to my colleague about pregnancy and children and she felt we were both very insensitive as she can't meet anyone and is unlikely to have children because of her age. Luckily my line manager didn't take it too seriously but I am astounded that someone can complain about this? We did not seek to offend her or anyone. It was simply sharing some good news.
AIBU to think the woman in my office had no right to complain about this?
