Unions were notified yesterday that the employees they represent would be informally told by their supervisors whether or not to report to work on Tuesday in the event of a federal government shutdown. Should a shutdown proceed, a majority of employees from the National Institutes of Health, the Bureau of Alcohol, Tobacco, and Firearms, the National Parks Service, and the Environmental Protection Agency, and the State Department would be furloughed, meaning that they would not report to work and would receive no pay, starting Tuesday. A little less than half of federal government workers would receive no pay at present, but would be required to report to work because they are deemed ?essential? to health or national safety. At the time this report is written, the Senate had passed a bill to fund the government that will still need to make its way through the House and then receive the President?s signature.
