The purpose of this legislation is to improve pay for certain employees of the Bureau of Prisons who work in areas designated as "Rest of U.S." This designation typically applies to locations that do not fall under specific locality pay areas, which can result in lower salaries for workers in those regions. The bill aims to ensure that these employees receive pay rates that are more comparable to those in nearby areas. Key provisions of the legislation include a change to how pay locality is determined for Bureau of Prisons employees.
