Filing a Workplace Harassment Complaint in Montana
Reviewed by DocDraft Legal Team - Montana - Last updated September 15, 2026
In almost every state, reporting harassment to HR and waiting for an answer burns the deadline. Montana is the exception. Mont. Code Ann. 49-2-501(4)(a) gives 180 days to file with the state, running from when the alleged unlawful discriminatory practice "occurred or was discovered," and 49-2-501(4)(b) extends that where you first tried to resolve the dispute "by filing a grievance in accordance with any grievance procedure established by a collective bargaining agreement, contract, or written rule or policy." An employer's written anti-harassment policy is a written policy on the face of that text. The extension has an edge to it that is worth understanding before you rely on it. If the internal process concludes within 120 days of the act or its discovery, you get 180 days from the conclusion of that process. If it does not conclude within 120 days, you get a flat 300 days from the act or its discovery, no matter how long the internal process goes on. A fast HR investigation buys you more time than a slow one, and a worker who waits politely for a long investigation to finish can run out of time while the file is still open. If your internal process passes the 120 day mark, count 300 days from the original conduct and act on that date. Complaints go to the Department of Labor and Industry, which does the work through its Human Rights Bureau, and the complaint must be written and verified under 49-2-501(3). Montana requires you to use that route. Mont. Code Ann. 49-2-512(1) makes the chapter "the exclusive remedy for acts constituting an alleged violation" and says a claim based on those acts "may not be entertained by a district court other than by the procedures specified in this chapter," reaching even claims that could otherwise be framed under Article II, section 4 of the Montana constitution. Coverage is not an obstacle here. Mont. Code Ann. 49-2-101(11) defines employer as "an employer of one or more persons or an agent of the employer," with no calendar week counting and no lookback, so essentially every Montana workplace is covered where federal Title VII would need 15 employees. If what you are facing includes physical assault, threats, or stalking, contact emergency services and speak with an attorney rather than starting with a complaint form. Attorney review is available if you want a second set of eyes before you file.

How long do I have to file a workplace harassment complaint in Montana?
The base period is 180 days. Mont. Code Ann. 49-2-501(4)(a) requires a complaint to be filed with the department within 180 days after the alleged unlawful discriminatory practice occurred or was discovered. That period can be extended under 49-2-501(4)(b) where you first filed an internal or contractual grievance. The federal EEOC charge deadline runs on its own clock of 180 days from the last incident of harassment, extended to 300 days where a state or local agency enforces a law prohibiting the same discrimination, so run both clocks rather than assuming the state one is always the earlier.
Does complaining to HR first extend my Montana deadline?
It can, and that makes Montana unusual. Mont. Code Ann. 49-2-501(4)(b) applies where the charging party has initiated efforts to resolve the dispute by filing a grievance in accordance with any grievance procedure established by a collective bargaining agreement, contract, or written rule or policy. An employer's written anti-harassment policy is a written policy on the face of that text. Note two limits: the statute speaks of the charging party filing the grievance, so an investigation the employer opened on its own may not qualify, and the statute does not define what counts as the conclusion of the procedure. Keep dated proof of your internal complaint and ask a Montana employment lawyer to confirm the extension applies to you.
How does the Montana extension actually calculate?
It turns on whether the internal procedure concludes within 120 days. If the grievance procedure concludes within 120 days after the practice occurred or was discovered, the complaint may be filed within 180 days after the conclusion of the procedure. If the procedure does not conclude within 120 days, the complaint must be filed within 300 days after the practice occurred or was discovered. The second branch is measured from the original conduct, so the extra time does not grow with a longer investigation.
Going through your employer's own complaint process can extend the state deadline here, but a slow process can also run you out of time.
Montana is the rare state where using your employer's internal complaint process can extend the filing deadline instead of consuming it. Mont. Code Ann. 49-2-501(4)(b) applies where the charging party has initiated efforts to resolve the dispute by filing a grievance under any procedure established by a collective bargaining agreement, contract, or written rule or policy, which on its face includes an employer's written anti-harassment policy. Keep proof that you filed the internal complaint and the date you filed it, because the extension depends on it. This is a high value provision and it is worth confirming with a Montana employment lawyer that your internal complaint qualifies.
Relevant Laws
Mont. Code Ann. 49-2-501(4)(b): An Internal Grievance Can Extend the Deadline
Where the charging party initiated efforts to resolve the dispute by filing a grievance under a collective bargaining agreement, contract, or written rule or policy, the complaint may be filed within 180 days after the conclusion of that procedure if it concludes within 120 days. Otherwise the complaint must be filed within 300 days after the practice occurred or was discovered.
Mont. Code Ann. 49-2-512(1): The Human Rights Act Is the Exclusive Remedy
The chapter is the exclusive remedy for acts constituting an alleged violation, including acts that may otherwise violate the discrimination provisions of Article II, section 4 of the Montana constitution, and a district court may not entertain such a claim except by the procedures in the chapter.
Mont. Code Ann. 49-2-101(11): One Employee Makes an Employer
Employer means an employer of one or more persons or an agent of the employer. The exemption for a fraternal, charitable, or religious association or corporation applies only where it is not organized for private profit or to provide accommodations or services available on a nonmembership basis.
Regional Variances
How Montana differs
The extension splits at 120 days, and the slower
The extension splits at 120 days, and the slower branch is the worse one. If the internal grievance procedure concludes within 120 days after the conduct occurred or was discovered, the complaint may be filed within 180 days after the conclusion of that procedure. If it does not conclude within 120 days, the complaint must be filed within 300 days after the conduct occurred or was discovered, measured from the original event rather than from anything the employer does. So an investigation that ends at day 110 leaves you until day 290, while one that drags to day 280 leaves you 20 days.
You can time out while HR is still investigating
You can time out while HR is still investigating, and nobody will tell you. Once an internal process passes 120 days, the deadline is a flat 300 days from the act or its discovery, and it keeps running while the employer takes statements, schedules meetings and drafts findings. Do not treat an open internal investigation as a reason to wait. Put the 300 day date in your calendar and file with the Department of Labor and Industry before it arrives, whether or not the employer has finished.
The Montana clock has a discovery rule written into
The Montana clock has a discovery rule written into the statute itself, which is unusual. Mont. Code Ann. 49-2-501(4)(a) runs the 180 days from when the alleged unlawful discriminatory practice "occurred or was discovered," rather than from the act alone. That is not the same as a rule about continuing conduct, and nothing in 49-2-501 says the clock runs from the last incident in a pattern. Record the date you learned what was happening as well as the dates of the incidents, and ask a Montana employment lawyer before counting from a later date.

Frequently Asked Questions
Yes, and this is the trap in the provision. Once an internal process runs past 120 days, your deadline is a flat 300 days from when the harassment occurred or was discovered, and that clock keeps running while the employer continues investigating. An investigation that finishes at day 110 leaves you until day 290; one that is still going at day 280 leaves you 20 days. Do not wait for a finding before filing with the Department of Labor and Industry if the 300 day date is approaching.
The statute accounts for that directly. Mont. Code Ann. 49-2-501(4)(a) runs the period from when the practice "occurred or was discovered," which is a discovery rule written into the statute rather than into an agency rule or a case. It is not the same as a rule about a continuing course of conduct, and nothing in 49-2-501 says the clock runs from the last incident in a pattern. Record the date you learned what was going on alongside the dates of the incidents themselves, and get the start date confirmed before you rely on it.
Yes, and the requirement is unusually strong. Mont. Code Ann. 49-2-512(1) makes the chapter the exclusive remedy for acts constituting an alleged violation, including acts that may otherwise also constitute a violation of the discrimination provisions of Article II, section 4 of the Montana constitution, and provides that a claim based on those acts may not be entertained by a district court other than by the procedures specified in the chapter. There is no right-to-sue letter in the Montana scheme. The route to court opens on a notice of dismissal, after which 49-2-511(3)(a) allows 90 days to commence a civil action in district court.
You have two moves and both are on short clocks. Under Mont. Code Ann. 49-2-511(1) you have 14 days to file objections with the Commission for Human Rights. Under 49-2-511(3)(a) you may instead commence a civil action for relief on the merits in district court within 90 days, and the statute is explicit that failing to commence in time bars the claim. The statute describes the start of that 90 days in slightly different terms in different sentences, so treat the date on your notice as day one and speak with a Montana employment lawyer immediately rather than calculating it yourself.
Not necessarily. Mont. Code Ann. 49-2-501(5) provides that if the department determines the complaint is untimely, it shall dismiss the complaint on a finding of no reasonable cause. Because a no reasonable cause dismissal is one of the dispositions that opens the district court route under 49-2-511(3)(a), the timeliness question can still be put to a judge in a civil action commenced within 90 days. Given the extension in 49-2-501(4)(b), an internal grievance you filed may matter a great deal to that argument, so gather the dates before you talk to a lawyer.
Only if you appeal in time, and the window is 14 days. Mont. Code Ann. 49-2-505(3)(c) provides that if a hearings officer's decision is not appealed to the Commission within 14 days as provided in subsection (4), the decision becomes final and is not appealable to district court. If you do appeal and the Commission issues a final agency decision, court access is by petition for judicial review within 30 days under 49-2-505(9), which is review of the agency record rather than a fresh trial. This is why a reasonable cause finding, which sounds like the better outcome, leads to narrower court access than a dismissal does.
Mont. Code Ann. 49-2-101(11) defines employer as an employer of one or more persons or an agent of the employer, with no calendar week qualifier, so a single employee makes a covered employer where federal Title VII needs 15. The exemption for a fraternal, charitable, or religious association or corporation applies only where the organization is not organized for private profit or to provide accommodations or services available on a nonmembership basis, so a religious nonprofit serving the general public stays covered. The characteristics listed in 49-2-303(1)(a) are race, creed, religion, color, national origin, age, physical or mental disability, marital status, and sex; sexual orientation is not among them. Age is defined at 49-2-101(1) as number of years since birth, with no minimum, so a young worker is protected as well as an older one.
