The main purpose of this legislation is to provide financial relief to federal employees, contractors, and certain states affected by government shutdowns. It aims to reimburse these individuals and entities for costs incurred due to the loss of income during periods when the government is not funded. Key provisions of the legislation include defining who qualifies for reimbursement, known as "covered employees." This includes federal employees who are furloughed, those required to work without pay, and contractors placed on unpaid leave.
