Would you know if your job was slowly injuring you?
Most employees wouldn’t. There isn’t a big accident. No ambulance. Just a wrist that gradually hurts more and more each week until suddenly you can’t type an email or lift a box.
That’s a repetitive strain injury.
And it’s much more common than many people realize. Repetitive motion musculoskeletal disorders account for 28% of all serious injuries and illnesses across private industry — nearly one in three.
The good news?
RSIs rank among the easiest workplace injuries to prevent. All you need to know is what to look for.

What Is A Repetitive Strain Injury?
A repetitive strain injury occurs when muscles, tendons and nerves are damaged by repeating the same action continuously.
Typing. Scanning groceries. Turning. Holding a power tool. Repetition. Any movement done thousands of times per day causes tissue to break down faster than the body can heal itself.
It builds slowly, and that is exactly what makes it dangerous.
The most common repetitive strain injuries include:
- Carpal tunnel syndrome
- Tendonitis and tenosynovitis
- Bursitis in the shoulder, elbow or knee
- Tennis elbow and golfer’s elbow
- Rotator cuff strain
- Trigger finger
Here’s where it gets complicated…
When there is no single accident to point to, repetitive motion claims are denied far more often than your run-of-the-mill broken bone from a slip-and-fall. The insurance company will blame the pain on your hobby, on getting older, or even from a previous job the worker had five years ago. For that reason, employees filing workers’ compensation claims due to a repetitive motion condition will often speak with a worker’s comp attorney early in the process. A workers comp attorney will connect medical evidence to actual job duties, protect your lost wage and medical benefits, and keep the claim moving when the insurer pushes back.
Remember: reporting an injury as soon as possible is critical. There are deadlines in workers’ comp, and an untimely report is one of the first arguments an insurance company will make to deny a claim.
The Real Cost Of Repetitive Motion At Work
The scale of this problem is bigger than most employers admit.
Over 2023 and 2024 there were 937,620 musculoskeletal disorder cases with days away from work, job restriction or transfer in the private sector alone. That’s not an “edge case” — that’s nearly a million people who got injured on the job to the point their bodies failed them.
And these injuries don’t heal quickly.
The average serious workplace injury results in lost time from work of greater than one full week. To an hourly employee that means a loss of hard earned wages. To a business it means overtime, retraining and disruption.
Oh and then there’s the bill. Physical strain due to lifting, pushing and carrying costs employers in the US $13.7 billion annually, and has been ranked as the leading cause of serious workplace injury for 25 consecutive years.
Think about that for a second.
25 years in a row with the same injury leading the list. That’s some accepted danger right there.
Office Workers: The Slow Burn Injury
Desk work looks harmless.
No, it doesn’t. Typing at an improperly adjusted desk all day means that your wrists, neck, shoulders and lower back are under low-level stress for eight hours straight. There’s no acute injury like banging your head. It’s just constant pressure that may take months to become noticeable.
The usual culprits are:
- A keyboard or mouse that forces the wrist to bend upward
- A monitor set too low, pulling the neck forward
- A chair with no lumbar support
- Cradling a phone between the ear and shoulder
- Working from a laptop on a sofa or kitchen table
Remote and hybrid working aggravated the problem. Working from home means your desk setup is unlikely to have been ergonomically assessed, and there’s no one strolling by your desk telling you to sit up straight.
The consequence? A generation of office workers walking around with neck pain and numb fingers who think this is normal. It’s not normal. It’s a warning sign.
Manual Workers: Where The Damage Adds Up Fast
Manual and industrial work does the same damage, only faster.
Warehouse pickers. Nurses. Meat processors. Electricians. Hairdressers. Construction crews. Delivery drivers. They all use forceful, repetitive motions while racing against the clock. Mix in vibrating power tools, cold temperatures or frequent overhead reaching and risk increases exponentially.
The problem with these jobs is this: the pace is almost always dictated by others. Scanner beeps, assembly line speeds, package quotas. You can’t just take it slower when your shoulder begins to hurt, so you work through until the injury screams at you to stop.
That is when a manageable strain becomes surgery and months of lost income.
Warning Signs That Should Never Be Ignored
RSIs don’t suddenly happen. You have lots of warning. Most people choose to ignore the warnings.
Watch for:
- Aching or burning pain during or after a shift
- Tingling, pins and needles, or numbness in the hands
- Weakness or a tendency to drop things
- Stiffness that takes longer to shake off each morning
- Swelling, tenderness or reduced grip strength
There’s an easy rule to remember. If pain persists after sleeping or recurs on the same days each week, then it’s job related.
Have it diagnosed by a physician and report it to the employer in writing. That written documentation is the foundation of your claim.
How To Prevent An RSI Before It Starts
Prevention is far cheaper than treatment, and most of it costs nothing at all.
Fix the workstation first. Keep elbows approximately 90 degrees; keep wrists straight; position monitor at eye level; and keep feet on the floor. Manual workers should be provided tools that are properly sized to the hand, and materials to be lifted should be stored between knee and shoulder height so that no one has to bend or reach overhead all day long.
Break up the repetition. Job rotation is your best friend. Rotating jobs every few hours allows one group of muscles to rest while another works.
Take proper micro breaks. 30 seconds to a minute of stretching every 30 minutes is better than one long break at lunch.
Seek care early. Employers should train workers to identify these injuries and report them early. Early reporting is what turns a two week recovery into a two year recovery.
Bringing It All Together
RSIs are silent, progressive and 100% preventable. That’s what makes them so aggravating.
To recap:
- They come from repeated movement, not one accident
- Office and manual workers are both at serious risk
- Pain, tingling and weakness are warnings, not inconveniences
- Ergonomics, rotation and breaks stop most of them
- Early reporting protects both the body and the claim
No one should have to give up using their hands to earn money. Listen to your little pains now. The body only tells you once.
