All bosses are control freaks to some extent. They like things done there way. They sign the check so what's wrong with doing it their way? Remember, it all pays the same. Even though you may know of a better way of doing something, keep it to yourself. You may one day be the boss and you can be the control freak.
Getting the job done in a specific manner according to your boss, even though you know of an easier, quicker way, is your boss being a control freak.
Having been a boss, and also having had bosses, I wonder if you are saying this boss is a micro manager. If that is what you are talking about, then yes, it is a total pain, and typically, micro managers have limits - they can only control just so much. Past that they fail, and as a boss they fail.
bosses are supposed to have control but not be freaks about it. i never had a boss who was a control freak but i worked with a lot of control freaks who thought they were bosses.
My president is one. :(
