Your Body Wore Down on the Job. Minnesota Workers' Comp Should Cover That.

Cumulative trauma injuries — called Gillette injuries under Minnesota law — are among the most commonly denied workers' comp claims. Insurers bet that you don't know your rights. We've spent 18 years proving them wrong.

What Is a Gillette Injury in Minnesota Workers' Compensation?

A Gillette injury is a legal term for a cumulative trauma condition — an injury that develops gradually over time from repetitive job duties rather than from a single accident. The name comes from a 1966 Minnesota Supreme Court case, Gillette v. Harold, Inc., which established that workers have the right to compensation for injuries that build up over months or years of physical work.

Under Minnesota workers' compensation law, a Gillette injury becomes compensable at the point when the cumulative wear and tear from your job duties causes a condition serious enough to disable you or require medical treatment. You do not need to point to a single incident. The repetitive nature of your work itself is the cause.

Common job types and activities that produce Gillette injuries include:

• Repetitive lifting, loading, or carrying in warehouse and manufacturing work
• Sustained overhead work in construction, painting, and electrical trades
• Prolonged vibration exposure from heavy equipment, jackhammers, and power tools
• Repetitive bending, kneeling, and squatting in flooring, plumbing, and pipefitting
• Assembly line work involving repetitive hand, wrist, and shoulder motion
• Extended driving or operating heavy machinery in mining and logging

Why Insurers Deny Gillette Injury Claims — and Why Those Denials Often Don't Hold Up

Cumulative trauma claims are harder for insurers to dispute with a single document, so they use that ambiguity against you. The most common denial tactics we see are worth understanding before you accept a denial as final.

"We Can't Identify a Specific Work Incident"

This is the most frequent denial language on Gillette claims, and it reflects a deliberate misreading of the law. Minnesota workers' comp does not require a single incident for a cumulative injury claim. The insurer knows this. The argument is designed to discourage workers who don't have legal representation from pushing back. A Gillette injury claim is built on your work history, your job duties, and medical evidence connecting those duties to your condition — not on a single accident report.

"Your Condition Is Due to Age or Pre-Existing Factors"

Insurers frequently attribute repetitive stress injuries to aging, arthritis, or prior conditions rather than your job. Minnesota law does not require your work to be the sole cause of your condition — only a substantial contributing cause. If years of physical labor accelerated or aggravated a condition that might have otherwise remained manageable, that contribution is compensable. We build the medical record that establishes that connection.

What a Gillette Injury Claim Actually Requires

Building a successful cumulative trauma claim in Minnesota takes preparation and medical documentation. These are the core elements:

• A clear record of your job duties and how long you performed them
• Medical evidence from a treating physician connecting your diagnosis to your work activities
• A documented point in time when the cumulative injury became disabling or required treatment — this is the legal "date of injury" for a Gillette claim
• Proper notice to your employer once you knew or should have known your condition was work-related
• In many cases, an independent medical examination or expert opinion to counter the insurer's position

The notice requirement catches a lot of workers off guard. If you've been treating a shoulder, back, or wrist condition for years without connecting it to your job, the clock on your claim may not have started yet — but it needs to start soon. Waiting is the one thing that genuinely hurts a Gillette claim.

Related Workers' Comp Issues We Handle

Gillette injuries often overlap with other claim types — a cumulative trauma condition that goes untreated long enough can become a denied claim, and physical injury at work can produce psychological harm alongside the physical. We handle these connected issues in the same practice:

• Denied workers' comp claims in Minnesota, including claims denied on cumulative trauma grounds — see our denied claims page for more on the appeals process
• PTSD and psychological injury claims for workers whose job conditions produced mental health harm alongside or independent of physical injury — see our PTSD and psychological injury claims page
• Union workers' comp representation for trades members navigating claims that intersect with union agreements — see our Union workers' comp representation page

18 Years Representing Workers With Cumulative Trauma Claims in Minnesota

We've handled Gillette injury claims across the full range of trades and industries where repetitive physical work is the norm — construction, mining, manufacturing, warehousing, and the skilled trades. These are not easy claims to build, and they are not cases where a general practice attorney with a workers' comp checklist is going to serve you well.

Our practice is limited to workers' compensation and Social Security Disability. We know how Minnesota insurers approach cumulative trauma denials, what medical evidence moves these cases, and how to put together a claim record that holds up at hearing if it comes to that. If you're working with a union, we understand how collective bargaining agreements intersect with your comp rights. If your claim has already been denied, we know where the denial is likely to be vulnerable.

We serve injured workers across the Twin Ports region and the Iron Range, including clients in Duluth, Superior, Hibbing, Virginia, and Grand Rapids. There are no fees unless we recover for you.
