The Equal Employment Opportunity Commission, which was closed during the federal government shutdown, reopened on Monday. However, its Respondent Portal (where employers upload their responses and enter contact information) remained closed. Users were redirected to a page saying that the agency was still shut down.
Until today. The portal is back up again, and I can personally attest that it works.
The U.S. Department of Labor (which includes the Wage and Hour Division, the Occupational Safety and Health Administration, and the Office of Federal Contract Compliance Programs) remained open throughout the shutdown, as did the National Labor Relations Board.
