Agreed, I can't trust any article that starts with "I was so excited to become a manager". Direct managers (that is, low level ones) basically have fixed budgets, resources, schedule, and new ones have little political power or leverage. It's a SHIT job, and basically it is something a manager has to go through to get up to the better paying levels. And as stated, this guy basically was selling out his reports for his ambition to try to do "extra work". This guy was an AWFUL manager. The liberal diversity thing is so blatantly obviously a cover for him selling out his team rather than have the blame for his failure rest on him. Yes there are tensions in any team, guess what, that meant you had passionate team members.
