I know just how Brutus feels. I can work my ass, be great at my job and well-liked by everyone but I will never get promoted or be given any sort of authority. Brutus unfortunately has worked in the same place for 25 years. What I find kind of strange is that in some strips, Brutus is shown as a peon, someone near the bottom of the corporate ladder despite having seniority or just about everyone there. In other strips, he's shown as Veeblefester's right hand man who just doesn't get respect or a decent paycheck.
Whatever the scenario, thank God for rocking chairs.
