i think the "YES SIR" was being implied to saying "yes sir" to your boss.... you are not really your own boss and "running your own business" as erac advertises.... you actually become a "yes man" to your boss or your boss's boss... the more you move up the less control you actually have over your own career. as an MT you actually have the most control over your own career. after that it is a crapshoot.....
