why does a government shutdown happen

A government shutdown happens when the legislative branch, such as the U.S. Congress, fails to pass key funding bills to authorize government operations by the start of the fiscal year or before the current funding expires. Without an approved budget or temporary funding measure, the government must stop non- essential services, furlough non-essential employees, and only keep essential personnel working without pay until a funding agreement is reached. This impasse often occurs due to political disagreements between parties over spending priorities, such as healthcare or other budget issues, preventing consensus on a spending bill to finance government services. Shutdowns result in disruption of some government services, delayed pay for federal workers, and economic impacts due to halted operations and furloughs.
