1. Poor interpersonal skills. Horrible managers look down on you from on high like irascible emperors. They are insensitive, cold and as likely to be nice to you as give their pay-checks to charity.
2. Can’t get the work done. They repeatedly set overly ambitious targets and then repeatedly fail to meet them. They don’t follow through on their promises and they’re likely to betray your trust.
3. Can’t build a team. It’s perhaps the most essential skill of being a manager. Team-building requires building trust, assigning roles and goals, promoting good communication and providing leadership. Terrible managers are totally incapable of any of this.
4. Can’t cope with promotion. Who knows how they got that promotion, but it’s clear the new job is beyond them. As soon as they’re settled in, everything starts to fall apart.
