WGN Postal service may shut down for winter WGN News 3:03 PM CDT, September 5, 2011 Without emergency funding the postal service may have to shut down for the winter. The U.S Postal Service faces a $9 billion dollar deficit. The New York Times reports the agency doesn't have enough money to pay its bills and a $5.5 billion dollar payment is due this month. Possible cost cutting measures include eliminating Saturday delivery, closing up to 3700 post offices and laying off 120,000 workers. A congressional hearing on the matter is set for Tuesday.
