I’m having issues with a colleague, “Jane”. She is the assistant in our team and looks after a large number of clients with a lower value. I’m in a more senior role and look after a smaller number of clients with a higher value (the clients I have are more complex and need more intensive work, hence not having as many). This is a standard model in our profession. We are both managed by the same person who I suspect may have ASD and isn’t great as a manager.
Jane is constantly contradicting me in meetings, even over silly things and even if it means contradicting herself. In a recent meeting, Jane told me overtly that she doesn’t think I have enough clients and spend too long working on my accounts. She went on about her work with another company, as though I don’t have years of experience in my profession. I tried to counter that my accounts need more work, as is generally accepted. I am reaching targets set by my boss and get good feedback. My boss just sat and said nothing while Jane went on a complete rant at me. Jane used to do a more senior role elsewhere before taking time out for kids and she is obviously very unfulfilled and bored and taking it out on me. I’m always polite to her, generally just go along with what she says and avoid giving her admin, even though it is in her remit. But this is starting to make me ill with stress - I feel like I’m prepping for a fight before I go into meetings. My manager is useless and doesn’t pick up on social cues and didn’t see an issue. The other person in the team is good friends with Jane but even she thinks she has been out of line in the way she speaks to me. Do I escalate to HR?
