This bill aims to protect federal employees and military personnel from certain financial fees during periods when federal agencies are operating without appropriations. It specifically prohibits financial institutions from imposing insufficient funds fees on accounts held by eligible individuals during such government shutdowns. Additionally, the legislation prevents card issuers from charging late payment fees on credit cards, including government purchase cards, if the payment due date occurs during a covered period. These protections apply to individuals employed in the civil service, Armed Forces, or uniformed services who are either furloughed or working without pay during the shutdown.
