Montana is the only state in the United States that prohibits at-will employment after the probationary period. The Wrongful Discharge from Employment Act requires employers to have "good cause" to terminate a non-probationary employee - a protection that has no equivalent anywhere else in the country. Bozeman is one of the fastest-growing cities in the US, with a booming tech scene. Billings and Missoula anchor significant healthcare and professional services workforces. WorkGenius becomes your legal employer, manages WDEA compliance on every hire, and handles every Montana obligation from day one.

Montana's Wrongful Discharge from Employment Act (WDEA), enacted in 1987, makes Montana the only state in the US that has abolished at-will employment for non-probationary employees. It does not reach every worker: an employee covered by a written collective bargaining agreement, or by a written employment contract for a specified term, sits outside the Act. Under the WDEA, once an employee has completed their probationary period - which defaults to 12 months under HB 254 (2021) if the employer does not specify a different period, and which together with any extension may not exceed 18 months - the employer must have "good cause" to terminate them. Good cause means a legitimate business reason that is not arbitrary, capricious, or unlawful. Employees who are wrongfully discharged under the WDEA can recover lost wages and benefits for up to 4 years, plus punitive damages in cases of malice or fraud. For employers accustomed to at-will employment in every other state, Montana requires a fundamentally different approach to documentation, performance management, and termination.

Montana has a statutory non-compete ban for health care providers. MCA 28-2-724, enacted in 2023 and amended in 2025, provides that a contract may not restrict a health care provider's right to practise after the employment relationship ends. It sits alongside the general rule in MCA 28-2-703, which already voids most restraints of trade. WorkGenius screens every Montana health care hire against it.
Montana is the only US state that prohibits at-will termination after the probationary period. Good cause - a legitimate, non-arbitrary business reason - is required. Probationary period defaults to 12 months under HB 254 (2021), capped at 18 months including any extension. Wrongful discharge remedies include up to 4 years of lost wages and benefits, plus punitive damages. WorkGenius documents every Montana termination to meet the WDEA standard.
MCA 39-3-204 sets no statutory pay frequency - the duty is to pay on the regular payday you have established and not withhold beyond it. Final wages for involuntary terminations are due immediately on the day of discharge - one of the strictest final pay requirements in the US. Employees who resign are paid on the next regular payday. Late final pay can result in penalty wages.
Applies to all employers with 1 or more employees. Prohibits discrimination based on race, color, religion, national origin, sex, age, physical or mental disability, and marital status. The Montana Human Rights Bureau handles administrative complaints. The 1-employee threshold makes MHRA one of the broadest anti-discrimination statutes in the country.
Montana starts from a statutory ban, not a reasonableness standard. MCA 28-2-703 provides that any contract restraining someone from exercising a lawful profession, trade or business is void, except as provided by 28-2-704 (sale of business goodwill) and 28-2-705 (partnership dissolution). Montana courts have carved out a narrow judicial exception for employee covenants that are reasonable in scope, but the default is void and they will strike rather than modify an overly broad agreement. Given that and the WDEA's good cause protections, well-drafted NDAs are a more reliable tool than non-competes in Montana.

Montana enacted the Wrongful Discharge from Employment Act in 1987 as a compromise between complete at-will employment and the stronger job security protections found in European labor law. The result is a system where employers have maximum flexibility during a defined probationary period (defaulting to 12 months since HB 254 in 2021), but must have a documented good cause to terminate after that period ends. "Good cause" means a legitimate business reason - documented poor performance, policy violations, restructuring, or similar - that is not arbitrary or pretextual. Terminating a non-probationary Montana employee without documented good cause exposes the employer to claims for up to 4 years of lost wages plus punitive damages. WorkGenius builds WDEA-compliant performance documentation and termination procedures into every Montana employment relationship.
Under the WDEA, the probationary period is the initial period of employment during which the employer evaluates whether the employee meets the job's requirements. If the employer does not specify a probationary period in writing, HB 254 (2021) makes it default to 12 months - it was 6 months before that amendment. Employers can set a different period by specifying it clearly in the employment agreement or employee handbook, but the original period plus any extension may not exceed 18 months. During the probationary period, at-will termination applies and no good cause is required. Once the probationary period ends, the good cause requirement kicks in. WorkGenius documents the probationary period in every Montana employment agreement and tracks when each employee transitions to WDEA protection.
The WDEA 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 reasons. Courts have found good cause in: documented performance deficiencies after warnings, policy violations, insubordination, dishonesty, position elimination due to legitimate restructuring, and misconduct. Courts have rejected "good cause" where the stated reason was pretextual, where the employer failed to follow its own progressive discipline policy, or where the termination was actually motivated by discrimination or retaliation. Documentation is everything - WorkGenius maintains contemporaneous performance records for every Montana employee.
Yes. Montana requires employers to pay final wages immediately upon involuntary termination - on the day the employee is discharged. This is one of the strictest final pay requirements in the US, comparable to California and Oregon. For employees who resign, final wages are due on the next regular payday. WorkGenius has same-day final pay disbursement ready for every Montana termination - the payment is processed on the day of discharge, eliminating penalty wage exposure.
Montana simplified its income tax structure in 2024, and HB 337 (2025) reset the brackets again for tax year 2026: 4.7% on income up to $47,500 for single filers ($95,000 for joint filers, $71,250 for head of household), then 5.65% above that. This replaced a prior system with rates from 1% to 6.9% across multiple brackets. Montana withholding was also realigned to the federal standard deduction, eliminating Montana allowances. WorkGenius applies the current bracket structure to all Montana employees.
Montana courts enforce non-compete agreements under a reasonableness standard, but given Montana's WDEA good cause protections, non-competes face additional scrutiny: they must not be so broad as to effectively deprive an employee of any livelihood after discharge, particularly given that the WDEA itself provides significant job security. Courts will void agreements they find unreasonable rather than modify them. For employers seeking to protect confidential information and customer relationships in Montana, well-crafted NDAs and non-solicitation agreements are often more reliable than broad non-competes.
