One of the strange things about this industry is the way it sometimes nurtures and protects characters who end up in jobs and management way beyond their ability. (The two types often sustain each other) Promotion can be fast and unmerited ..but the fall into ignominy and obscurity can be cruel and even faster.
as the old saying goes ...."Best to treat colleagues well on the way up... because you never know who you might meet again on your way down."
there will be few tears shed if the reported predicament of a certain manager are correct.
