This legislation amends Title 5 of the United States Code to introduce a new system for federal employee relocation. It grants agencies the authority to provide a one-time lump sum payment to employees who are relocated in the interest of the Government. This lump sum would serve as an alternative to other traditional relocation expense reimbursements, streamlining the process for eligible employees. The bill mandates the Administrator of General Services (GSA) to establish comprehensive regulations for the implementation of this new authority. These regulations will specify the conditions under which agencies may authorize a lump sum payment, detail the methodology for calculating the lump sum amount , and outline procedures for employees to dispute relocation expense claims, including their right to appeal to the Civilian Board of Contract Appeals.
