I would respond, including everybody, saying I’m so sorry to hear that’s the way you feel. I’ve always thought you were very professional until I received this public message. In the future could you please show me a little respect by talking to me directly with any issues. Thank you in advance @WaffleandliesToday at work a woman (same level of seniority) of me sent a teams message meant for someone on her team, to a group wide teams chat I’m in, making derogatory comments about me. I’ve not worked with her for over 9 months and they were irrelevant to what I was doing at the time.
I have to keep working with her, any suggestions how I move forward?
Also would just make you manager and HR aware
Btw this also depends on what she said. I let a lot of things slide and would approach like this. But there are a few things in life I would absolutely have a HR meeting for
