Boyle's Law -- Talent in staff work or sales will recurrently and incorrectly be interpreted as managerial ability.
Sound familiar? I used to work for a company that was humming along, doing what we do, for a boss we enjoyed immensely. Of course that in and of itself had to a be problem, right? Right.
So the new upper swingin' you-know-what's decided to send our man out to pasture and bring in their own "yes man". Of course the Yes Man immediately tried to captialize on our previous accomplishments and in fact was able to report some outstanding reports of achievement since he took over the management of our division. The problem was that the work product was a function of his predecessor, and us underlings. And oh yeah, he was and probably still is the most incomplete, dysfunctional, derelict ever to be called a manager. So when he was publically honored for 'his' accomplishments, the world really knew that he was just a tool.
This law (not to be confused with the law by the same name that refers to the much less entertaining topic of thermodymanics) I'm sure can be seen in more places than just my resume.
