IMO the worst attribute a manager can have is low self-esteem.

I've seen it manifest as having a chip on their shoulder. This can be toxic. I've seen rational design discussions into relentless arguments where the conclusion is "let's agree to disagree".

I've also seen it manifest as a boss that does not have the respect of his team and people just kinda do their own thing because he is not willing to confront people and hold them accountable to their work.

I've also these two types work together and it makes for a very dramatic, toxic and down right unprofessional work environment.
