# At-will employment (US)

## Summary
In most US employment, an employer can fire a worker for any reason or none, and the worker can quit freely, except for illegal reasons such as discrimination, retaliation, or protected leave. Contracts, union agreements, and civil service rules can override it; Montana is the main statutory exception.

> **General information, not legal advice. State law varies; confirm with your state labor agency or an attorney.**
