The main purpose of this legislation is to ensure that employees of the Bureau of Prisons receive their salaries even during times when the federal government experiences a funding lapse. This is crucial for maintaining the financial stability of the personnel who work in correctional facilities. Key provisions of the legislation include the allocation of necessary funds from the U.S. Treasury to cover the salaries of both correctional staff, such as guards and administrators, and non-correctional staff, such as support and maintenance personnel.
