We all work remotely and this colleague started later than me. We are parallel and she is in no way higher up than me. I noticed she started making subtle put downs a while ago, but I ignored. Then last week, in a client meeting which I was leading as my turn, she said at then end when I was trying to bring it to a close, "Oh Emergency is really rushing us through today"! We had covers all topics, we were in the last minute of time and the clients had nothing to add. She then brought this up in responses to the email I sent with the minutes.
She is domineering, loud, uses 1000 words when 10 would suffice, is the type of person who just had to say something. My problem is I am massively low in self esteem, although the company rate me highly. But I just don't know how to respond, I don't know what would be appropriate. I'm middle aged and this has never happened to me before. Any advice would be welcome, thanks.
