In an act of slight contrarianism, i would add another one to the list: trying way too hard to be the complete opposite of a "self-centered narcissistic control-freak".
It depends if they're deficient in terms of:
- Not protecting the team from unreasonable demands and/or blame from the organization
- Doesn't ensure the work environment stays civilized for all
- Doesn't lead or set an example where necessary
There are genuinely nice, civilized, respectable managers who aren't "trying too hard".
1, 2, and 5 are essentially the same sort of Cluster B issues. Related: The No *sshole Rule is a good book to read on how a single jerk can ruin a team, manager or not.
3 is treating others with contempt instead of equal humans.
4 is a lack of ability to delegate/trust/verify that ruins morale.
Everything listed here is patently obvious. Was hoping they were going to dig past the surface level obvious character deficiencies and talk about more subtle and nuanced traits certain good and bad managers had. Instead it was essentially- narcissists and narcissistic traits make bad leaders… yea no kidding.
