Mention the top habits of bad managers?

What I had experienced for a bad or I must say failure managers are;

1 – Discourtesy or No respect for subordinates.

2 – Poor communication or never communicate in time, update late about the event or decision.

3 – Lying – changing the statements frequently this cause anxiety among the juniors.

I agree with nine of them, No9 - Pride, there is nothing wrong with being proud of yourself and the things you do.

1. Lack of People Skills

2. Lack of Reason & Common Sense

3. Unreasonable Expectations

4. Micromanaging Employees

5. Lack of Consistency

6. Inability to Share Appropriate Blame or Praise

7. Embarrass employees in public

8. Don’t follow up on employee ideas

9. Ignore professional growth needs

10. Demand unrealistic rules of order

11. Ignore individual differences

Cocky and conceited managers are the worst managers!

nobody is perfect ! in my opinion a bad manager has bad communication skills, he is disoganised, he lucks self discipline and also self confidence.But if he was like that he shouldnt be a manager right?

I THINK TO TAKE CREDIT ONLY TO HIMSELF

We all have bad habits because  no one is perfect. I agree with Manisha's answer as she describes beautifully .
