"When a dozen men are harnessed to the same cart, one always pulls harder than the others, and when it's a question of promotion and seniority, it's easy to tread on the toes of the man ahead of you. At every word one utters one has to be on one's guard; one's never quite sure whether it isn't going to arouse the disapproval of the big bugs; there's always a storm in the offing."
