Without giving too much detail, I have been through a process with my manager where she wanted to make a major change to my role. I resisted this (explained my points and essentially begged her not to do this) and she rolled back the decision the following day. However during that meeting we got into a conversation where I felt she was accusing me of not doing enough within our team. I was pushing back giving examples etc but the connection dropped mid conversation. She refused to resume (I callled her straight away) and after 48 hours of not being sure what was happening, she contacted me to request a face to face 'managed meeting' with a third party.
I have a number of concerns, notably that the independent person is better known to her than to me, and that I don't know what her specific reasons are for not wanting to speak to me.
My biggest concern however is that I have a tendency to get very tearful if I feel I am being told off, or someone is being unfair or not listening. Given the meeting is only half an hour I can't risk not being able to get my side across because I'm a sobbing mess. Any top tips for how best to avoid this would be great.
