A few patterns I've seen: * Preaching about the virtues of a flat organizational structure, but making unilateral decisions. * Hiring people for a particular challenging job, but have them work on menial unchallenging tasks. * Creating multiple layers of management for a tiny team. * Facilitating post mortems that would be better facilitated by a neutral third party. * Using vague management speak as a deliberate strategy to never be held responsible for anything. * Rewarding politics with promotions. * Marginalizing experienced employees. * Talking too much about culture. * Trying to be the company “thought leader” instead of helping people do their best work. * Assuming that everyone underneath you views you as a career mentor. * Negging employees. * New hire managers: Firing incumbent employees after you’ve only been on the job for a few weeks. * New hire managers: Not doing 1:1s with everyone who reports to you. * New hire managers: Create sweeping changes like re-orgs after a few weeks on the job. * New hire managers: Doing things a certain way because it worked well at a previous company. * New hire managers: Changing office work hours to suit your personal life.
