Well, she's a member of my team actually. Three different people have spoken to me so say they don't like her attitude, don't like the way she has spoken to them or the tone of her emails. She has sent me emails which were very high-handed, so I know she has form for this. I knew she was very stressed at the time, so I said nothing, and she went off sick immediately after, for a few days, so I felt the opportunity had passed. One colleague emailed to tell me he no longer wants to communicate directly with her, but only through me which I think is unacceptable.
Clearly I can't change her attitude, or that of the other 3 people. However, they have brought this to my attention as her line manager, so I feel I need to do something. How on earth do I broach the subject with her? And what would I expect the objective of a meeting with her be: to have her accept that what she says/writes may get other people's backs up? To have her apologise (unlikely!).
