I work for a large software company and there is a planned reorganization to consolidate all the designers under a central organization. While normally I would have no issues with this, I've found out the new manager is a person (let's call him ABC) whom I have just met once before and that one time we've met, he was very dismissive of my ideas and opinions and even critical of my work experience and my skill level.
When my current manager informed me about the reorganization and asked me if I was comfortable with it, I mentioned my concerns (she was in the same meeting with me when we met ABC) and she agreed it might not be a good move and asked if I wanted to stay in the same team. I agreed and that information was communicated to the leadership of the centralized design team about my desire to stay in the current team.
Today I've just got an email from ABC's manager asking if we could chat about the reorganization and if I had any concerns.
I am trying to figure out how to handle the meeting and communicate my concerns. Any suggestions would be helpful.
