Roughly 700,000 federal employees are working without pay during the government shutdown, which recently became the longest in U.S. history.

The shutdown has suspended the work of at least 600,000 workers since Oct. 1. Many more employees are required to report to work without pay until funding is restored.

Ahead of the shutdown, departments designated a certain number of “essential” employees, such as air traffic controllers, that must work during the shutdown.

However, President Trump has been able to reprogram billions of dollars of funds to pay certain federal personnel that are essential to his political agenda — including active-duty military, federal law enforcement officers and immigration agents — who typically work without pay during shutdowns until funding is restored.

The White House recently left open the possibility that it might not follow its legal obligation to restore those workers’ back pay.

In early October, the Trump administration seized on the shutdown to lay off more federal workers, sending out notices to about 4,000 people across at least seven major federal agencies. The firings were delayed after a federal judge temporarily blocked the administration from proceeding with its proposed layoffs.

Here are agencies that Mr. Trump targeted for layoffs during the shutdown:

Note: Sept. 2024 and pre-shutdown figures for Homeland Security exclude U.S. Coast Guard. The figures shown here are an update to the administration’s originally announced figures, which the government said included data discrepancies and processing errors. The notices employees at the Environmental Protection Agency and Energy Department received said their position may be affected by future layoffs.

Here is a look inside each agency’s contingency plan, which details how employees could be affected and which activities and programs will continue or be suspended.

Methodology

Not all agencies explicitly stated the number of employees who must work and those who would be furloughed. In those cases, the numbers were calculated from additional information included in the plans, and may include some duplicate counts. Data does not necessarily reflect the most up-to-date employment numbers for an agency’s total work force; some agencies provided numbers based on personnel data from as early as March 2025.

Data is based on publicly available contingency plans from the Departments of Agriculture, Commerce, Defense, Education, Energy, Health and Human Services, Homeland Security, Housing and Urban Development, Interior, Justice, Labor, Transportation, Veterans Affairs, Environmental Protection Agency, Office of Personnel Management, Small Business Administration, Social Security Administration and Treasury.
