Requires certain federal agency heads to certify to Congress before carrying out major staffing, office-closure, or reorganization actions that those actions will not reduce benefits, increase delays, or limit outreach to people eligible for federal programs. Agencies must also provide a report explaining how they will reallocate resources to prevent those harms. Inspectors General must study and report on the real-world effects within one year, and if harms are found the agency must reverse the covered action. The rule and definitions take effect one year after enactment.
