  • Public policy exceptionRecognized by statute. Firing someone for refusing to break public policy, or for reporting a violation of it, is wrongful discharge (Mont. Code § 39-2-904, 1987). Source: mca.legmt.gov↗ (opens in a new tab)

At-will employment exceptions checklist for Montana employers

A simple order of work, based on the rules above. It is not a legal checklist.

  1. Say in your handbook and offer letters that employment is at will, and avoid promises of job security.
  2. Make sure handbook wording does not create a contract (add a clear disclaimer).
  3. Never fire someone for refusing to break the law, reporting wrongdoing, or using a legal right.
  4. Write down the real, lawful reason for each firing.
  5. Check federal and state anti-discrimination and leave laws before you act.
  6. Pay final wages on time; see our final paycheck guide for your state.
