Even a partial government shutdown could impact hundreds of thousands of federal employees -– with workers facing furloughs and unpaid labor -- depending on how much of the bureaucracy Congress agrees to fund in the next nine days.
Seven of 12 sections of federal appropriations remain unfunded, accounting for approximately 30 percent of federal workers. Negotiators have signaled that they’ve nearly reached consensus on six of the areas of appropriations, with an agreement on Homeland Security proving to be the most elusive due to disagreements over the president’s demand for $5 billion towards the border wall.
About 420,000 federal employees who are deemed “essential” would continue to work through a shutdown, ensuring that critical operations in government would proceed unhindered. But these workers would not receive any compensation until the shutdown ends and lawmakers pass legislation to pay them retroactively.
That includes federal employees at the Department of Homeland Security, where 54,000 border patrol employees and 53,000 Immigration and Customs Enforcement employees would continue working through a shutdown, though with their pay delayed.
The spending bills already approved by Congress and signed into law would keep departments operating in Defense, Labor, Education and Health and Human Services. Lawmakers have also cleared bills to fund the legislative branch, military construction, veterans affairs and energy and water development.
So what else could suffer from congressional gridlock? Here are the six areas of appropriations that lawmakers are still working to fund for fiscal year 2019, other than Homeland Security:
1. Department of Agriculture, Federal Drug Administration and Rural Development Routine inspections for food safety would stop, namely for pharmaceutical and plant food testing.
2. Commerce, Justice & Science Most of the Department of Justice’s employees are classified as essential, so they’ll continue working without pay. According to Sen. Patrick Leahy, the top Democrat on the Senate Appropriations Committee, there are 2,614 Bureau of Alcohol, Tobacco, Firearms and Explosives agents, 16,742 Bureau of Prisons correctional officers, 13,709 FBI agents, 3,600 deputy U.S. Marshals, and 4,399 Drug Enforcement Administration agents would have to wait for paychecks to come once the shutdown ends.
The special counsel’s investigation would also continue, as it is funded with a permanent, indefinite appropriation and all direct employees are excepted positions because their funding is not dependent upon an appropriation that requires renewal.
Most of the National Science Foundation would close down, and NASA would furlough 16,700 employees -– accounting for 96 percent of its staff.
3. Financial Services and General Government Most employees at the Internal Revenue Service -- 52,000 of them -- would be furloughed since the shutdown is months away from tax season and their jobs are not considered essential at this time.
Most U.S. Secret Service employees, tasked with protecting the president, his family and former presidents, would also continue working without pay.
The U.S. Postal Service will not shutdown four days before Christmas, contrary to any rumors suggesting otherwise.
4. Interior and Environment National parks, forests and presidential libraries would all send up to 80 percent of their employees home during a shutdown, though many facilities would remain operational with a skeleton crew. At the Environmental Protection Agency, workers involved in emergency environmental cleanup would continue working, though they’d likely be approved for retroactive pay after the shutdown. Almost everything else at the agency would shut down.
5. State and Foreign Operations Every U.S. diplomat stationed abroad is designated “essential” and most operations would continue, including the processing and issuance of most passports. Passport offices physically located inside another agency’s building would temporarily close if it is shuttered.
6. Transportation, Housing and Urban Development Investigations by the National Transportation Safety Board would halt, but air traffic controllers would still come to work –- to ensure the safety of the country’s commercial aviation.
One week prior to the possible expiration of appropriations, the Office of Management and Budget communicates with senior agency officials throughout the administration “to remind them of their responsibilities to review and update their lapse plans and to take other necessary steps to prepare for a potential lapse in appropriations, regardless of whether the enactment of appropriations appears imminent,” a senior Trump administration official said.
Funding for these seven appropriations titles expires at the end of the day on Friday, Dec. 21.
