Several years ago I wrote a book called Bleedership, Biblical First-Aid for Leaders. In the book, I contrast the leadership style of a tyrannical boss I had to the leadership style of some of the Bible's greatest leaders.
My boss was definitely a "bad boss." However, you don't need to be a tyrant to be in the bad boss category. On www.changingminds.org I just found an interesting article which begins like this:
As soon as the word bad boss is mentioned most people start imagining pictures of a wicked person, a crook, a tyrant, a scheming backstabbing individual, a selfish ogre, etc. And typical textbook definitions of a bad boss is one who screams, threatens, intimidates, grabs credit, fires people, throttles people’s necks and so on. While this could be true in some cases, it is not so in a large percentage of cases. Actually it is not necessary to be a wicked person at all to be called a bad boss. Ironically, a good natured or normal person can also fall under the category of a bad boss without exhibiting the standard boorish behaviors. Here are a few common mistakes good people do to slowly transform themselves into bad bosses.
