At-Will Employment Exceptions in Montana: The Only State That Is Not At-Will

Montana is the only US state that has rejected at-will employment by statute. The Wrongful Discharge from Employment Act requires good cause for termination after a probationary period, fundamentally changing the legal landscape.

Last reviewed:

Montana is the only state in the country that has rejected at-will employment by statute. The Wrongful Discharge from Employment Act (WDEA), codified at Mont. Code Ann. §§ 39-2-901 to 39-2-915, requires employers to have "good cause" for termination once an employee has completed the probationary period.

This is a structural difference. Where every other state starts from "the employer can fire you for any reason or no reason," Montana starts from "the employer must have a legitimate reason."

The rule, in plain terms

  • Default rule: Employees who have completed their probationary period (typically six months, but can be set by the employer up to 12 months) may only be discharged for "good cause."
  • Good cause defined: § 39-2-903 defines good cause as "reasonable job-related grounds for dismissal based on a failure to satisfactorily perform job duties, disruption of the employer's operation, or other legitimate business reason."
  • Probationary period: During probation (default six months, employer may set up to 12), the employee is effectively at-will. After probation, the WDEA's good-cause rule applies.
  • Public policy: Even during probation, an employer may not discharge for reasons that violate public policy (refusing to commit a crime, reporting illegal conduct, taking statutorily-protected leave).
  • Express written employment contract: If the parties have an express written contract, the contract terms control — the WDEA does not override an at-will provision in a written contract.
  • Remedies: Wages and fringe benefits for up to four years from the date of discharge (less interim earnings), plus reasonable attorney's fees and costs.
  • Internal grievance procedures: If the employer has an internal grievance procedure, the employee must use it before suing. Failing to use it can be a defense.

Scripts to use

When fired after the probationary period:

"I have completed my probationary period of [N] months and have been employed since [date]. Under the Montana Wrongful Discharge from Employment Act (§§ 39-2-901–915), I am entitled to a written statement of the good cause supporting my termination. Please provide that statement within 14 days."

To invoke the public-policy exception during probation:

"I believe my discharge violates Montana public policy because I was terminated for [specific protected activity — refusing to commit a crime, reporting illegal conduct, exercising a statutory right]. Even within the probationary period, public-policy discharges are unlawful."

To trigger the grievance procedure:

"Per your employee handbook section [X], I am filing a formal grievance regarding my discharge on [date]. I request a hearing under the grievance procedure within the timeframe specified, and reserve all rights to pursue a WDEA claim upon completion of the procedure."

What to document

  • Your start date and the end of your probationary period
  • Your performance reviews and any written feedback
  • The employer's stated reason for termination, in writing
  • The employer's internal grievance procedure
  • Any protected activity preceding the termination
  • All written communications around the discharge

When to escalate

If you believe your discharge violates the WDEA:

  1. Complete the employer's internal grievance procedure if one exists — required before filing suit.
  2. File suit within one year of the date of discharge. The WDEA has a short statute of limitations.
  3. The WDEA permits arbitration if both parties agree; the employer may extend a written offer to arbitrate within 60 days of the employee's filing of a complaint.
  4. Consult a Montana employment attorney early. The WDEA is unique and most attorneys outside Montana are unfamiliar with it.

The WDEA fundamentally changes the negotiating posture in Montana. Severance offers and pre-termination conversations look different when both sides know the employer carries the burden of showing good cause for discharge.
