1. Don’t take responsibility for your mistakes.
Reasonable bosses know that no one is perfect and that mistakes will sometimes happen. What they care about is how you follow up on a mistake. If you make excuses, get defensive, or deny responsibility, your boss won’t trust that you understand why the mistake happened in the first place and what you need to do to prevent it in the future.
2. Be too sensitive to take feedback calmly.
If you routinely get upset, offended, or angry when your boss gives you feedback on your work, you’re making it hard (and painful) for your boss to do her job. Worse yet, she might start avoiding giving you important feedback that you need to hear.
3. Don’t take notes during a discussion of work that you’ll be doing.
When you’re having a nuanced discussion of a project, your boss wants to see that you’re capturing the details.
4. Guess instead of finding out an answer for sure.
Guessing means that some of the time, you’ll be giving out wrong information. Your boss will be making decisions or taking actions based on the information you provide, so it needs to be right.
5. Don’t disclose your biases.
It’s fine to have biases; we all do. But if you hide your agenda or biases from your boss and she eventually finds out, you’ll have destroyed your credibility with her.
6. Regularly vent about your frustrations without bringing them to your manager.
Everyone vents about their job (or their boss) sometimes. But if you find yourself routinely complaining to other people, it’s time to either talk to your manager or start keeping it to yourself.
