The issue is of cause that in many large companies some people jobs are more or less defined as keeping you from doing yours. The owner of a Danish consulting company once postulated that: "Many larger (Danish) companies could fire all of their CUSTOMERS, and 40 - 60% of the employees would still have a job to do." - His point being that a large part of the workforce isn't in anyway related to providing services or products to the customers. Having worked for a large telco, I wouldn't be surprised if he's right. The point is that a portion of these people, which doesn't really produce anything will eventually do something that distrupt the "makers", because they need to make their presents known.
