What would happen, who would be furloughed if U.S. government shuts down?
Much of the impact or relative lack of disruption is determined by whether agencies are partly funded by industry user fees or deemed to be essential services.
Here is a roundup of some of the impact that would be felt:
FEDERAL WORKERS: As many as 1 million federal employees could face unpaid furloughs or missed paydays, according to the president of the American Federation of Government Employees, which represents 670,000 union members.
THE WHITE HOUSE: The Executive Office of the President will furlough about 1,265 staff and retain 436 as excepted workers. Among the staff retained will be 15 to provide "minimum maintenance and support" for the White House. Executive agencies will be reduced to skeleton staff, including four at the Council of Economic Advisors.
ECONOMIC DATA: The United States will stop publishing much of its economic data if the government shuts down, including the closely watched monthly employment report.
U.S. SECURITIES AND EXCHANGE COMMISSION: The SEC would continue reviewing applications for initial public offerings (IPOs) and monitoring markets as normal in the early weeks of a government shutdown, and can continue operating fully for a few weeks, a spokesman said.
DEPARTMENT OF HEALTH AND HUMAN SERVICES: Signup for the new U.S. health exchanges under the Affordable Care Act due to start on October 1 will proceed. Across the vast department and its sub-agencies, about 52 percent of staff will be furloughed - some 40,512 workers. Among the programs shuttered would be the Centers for Disease Control's annual seasonal flu influenza program. The National Institutes of Health would not admit new patients in most circumstances.
U.S. FOOD AND DRUG ADMINISTRATION: Some 55 percent of the FDA's employees will be working. Of those reporting to work, 74 percent will be funded with fees paid to the FDA by the industries it regulates. The FDA's expert advisory committee meetings, which recommend whether the agency should approve new products, will for the most part continue. The next scheduled panel is on October 8 to recommend whether to approve expanded use of certain pacemakers and defibrillators from Medtronic Inc. <MDT.N>. The FDA will cease most of its food safety, nutrition and cosmetics activities, such as routine inspections of plants and facilities. It will also be unable to monitor imports, and will cease certain compliance and enforcement activities.
