Most large companies have a lot of dead weight. Not as much with smaller private concerns. Fortune 500 I worked for had, it seemed, about 1 million V.P.’s. We used to try to figure out what they did all day except send emails and bother us. Really like Dilbert.
It was easy to tell the dead weight because they were the ones constantly calling meetings, attending meeting and, worst of all, dragging out meetings which you couldn't avoid attending.
My best boss during that era had a standing agreement with me that if we were caught in a meeting for more than ten minutes after the scheduled finishing time, we would call the other back to the office due to great emergency. Said emergency generally had something to do with getting real work done.
