Do you feel like the walls of your cubicle are closing in on you? They are. The average office is getting progressively smaller:
In the 1970s, American corporations typically thought they needed 500 to 700 square feet per employee to build an effective office. Today's average is a little more than 200 square feet per person, and the space allocation could hit a mere 50 square feet by 2015,
This is both because of the recession and because young workers are more comfortable with small, collaborative work spaces. They aren't demanding walled offices (The Time piece of Zuckerberg made note of his lack of an office). If you would actually like an office, well, you may be out of luck. They seem to be going the way of the dodo.
