I'm looking for a short story, I believe by a 50s to 70s American author, about a guy who gets a coveted job at a huge Company making some unspecified products.
He gets promoted to the head office of the Company, located in a enormous pyramid-shaped skyscraper of over a hundred floors, where the higher your rank, the higher floor your office is on. The President's office is supposed to be at the apex of the pyramid.
But it's a strange company because while everyone works very hard, no-one has ever seen the President. The official line is that he is very busy. There are rumors that he is dead, or that he does not exist, and that nobody is in charge. Eventually a superior expiring on the job from overwork authorizes the protagonist to visit the company directors. He explores their offices near the top floor, which are full of the paraphernalia of their respective hobbies, but there is nobody there.
Finally he climbs to the very top tiny floor which turns out to contain the elevator motors. He finds a small window, looks out and sees that it is winter, and remembers that there is a world outside the Company.
