Office space per worker shrinking

The Wall Street Journal reports, in "Corporate Cram Bedevils Office Recovery: Trend of Companies Packing More People Into Less Space Picks Up Pace; A 'Tiny Library' at One Law Firm," that office space/worker is shrinking somewhat. The rule of thumb had been roughly 250 square feet per office worker, now it's 200 square feet per worker. That means more people will be working in typical office buildings.
