Unless you are independently wealthy or have been lucky enough to work for yourself all your life (and most of us fall into neither category,) chances are you’ve had a bad boss or two along the way.

You know the type: the boss who sets ambiguous tasks and then micromanages them. Who offers a grunt when you ace a project, but chews you over for 20 minutes because of a minor error. The one who will take credit up the chain for great work you do, but won’t cover for you when deadlines slip. And so on.

I was reminded of this in profiling a client recently. He had been doing everything right, killing himself to complete complex operations/IT projects, plus studying nights for an M.S. degree and co-managing a young family. His boss committed all of the above evils and more. She would casually set him ‘by-close-of-business today” tasks late in the day, interfere in carefully nurtured team relationships he had built up over months, use fear of termination to crack the whip, and the list goes on.

At the first possible moment, he quit. Yay.

Listening to this phase of his life, I felt need to reach for the Kleenex. But I could offer some consolation. After the event, what he had was fabulous experience for his future role as a manager and leader, and it would play well in an MBA admissions essay. Why? Because if you have experienced having your motivation sapped, having to walk on eggshells around an idiot who controls you, having to grind your teeth in frustration at not being able to implement an obvious innovation — that is, if you have been poorly managed yourself, you have excellent insight into what not to do. And therefore, reversing all that a bad boss does, you have a good idea what kind of boss you should be.

Further, for MBA admissions essay or interview purposes, your bad-boss story is “proof” you have been through fundamental learning about management, have developed insights into how to handle people under you, and are therefore ready to manage effectively when your turn comes. If you have a story like this, tell it.
