And just like that, my old boss is out. It's shocking really. 

The offical story is that his position was upleveled. That our devisions business is growing with such importantce that we need a revolutionary step forward in leadership. That we don't have time to allow the old leader to grow.

I've met the new boss. He is open and curious  He fully admits to not being part of the decision process, and doesn't know what really transpired.
