The agency cut nearly everyone who works to administer federal funding for the Individuals with Disabilities Education Act, one staffer said.

The U.S. Department of Education fired nearly everyone in the Office of Special Education and Rehabilitative Services in a wave of new layoffs that began Friday, according to the union representing the agency’s employees.

Without an official estimate from the agency, it wasn’t immediately clear how many people in the division were fired. Yet based on reports from staff and their managers, most employees below the leadership level were part of the workforce reduction, said Rachel Gittleman, the president of the American Federation of Government Employees Local 252.
