This bill expands workers' compensation benefits for civilian federal employees who were exposed to toxic burn pits while working overseas during military operations. The legislation creates a presumption that certain diseases listed by the Department of Veterans Affairs are automatically connected to burn pit exposure, eliminating the need for affected workers to prove the link between their illness and their job. Eligible employees include those from agencies like the Department of State, Department of Defense, Department of Justice, and intelligence community agencies who worked at least 30 days in countries where the U.S. was conducting military operations since August 1990. The list of covered diseases will initially match those already recognized for military veterans exposed to burn pits, and the Secretary of Labor must update this list within 90 days whenever the VA adds new diseases. The Secretary of Labor must also report to Congress within one year on how many civilian employees qualify for these new benefits.
