A government shutdown occurs when the federal government temporarily halts its operations due to a lack of funding. This situation typically arises when Congress fails to pass a budget or a continuing resolution to finance government activities. During a shutdown, non-essential services and programs may be suspended, affecting various government agencies and employees. During a shutdown, many federal workers, including those at agencies like the Internal Revenue Service and National Park Service, may be furloughed or required to work without pay. Essential services, such as emergency response and national security, usually continue to operate, but many public services and benefits may be delayed or unavailable.
