Episode 57 - Fixing Missing Stairs

This episode's question:

I have a member of my new team who is very senior, they have been around for a very long time and they are a huge pain. Everybody talks about how difficult the person is, how much they have to work around them, and how much they are a terror in meetings and in any group work. When it comes to review time everybody has perfectly generic and kind feedback for the person. The people that complain the most just don't provide feedback at all. How can I help this person grow or make a case to fire them if it comes to it if they won't give me information to work with?
