Workers’ Comp for Gradual Injuries
Not every workplace injury happens because of one obvious accident.
Maybe your back started hurting after months of lifting. Your wrist gradually became painful from repetitive computer work. Your shoulder began bothering you after years of reaching, carrying, or using the same equipment every day.
There was no fall, collision, or single moment when you can say, “That is when I got hurt.”
Can you still file a workers’ compensation claim in California?
Yes. California workers’ compensation law recognizes injuries that develop gradually from repeated work activities or exposures. These are commonly called cumulative trauma injuries or cumulative injuries.
What Is a Cumulative Trauma Injury?
California law distinguishes between a specific injury and a cumulative injury.
A specific injury results from one incident or exposure. For example, you fall from a ladder at work and injure your back.
A cumulative injury develops because of repetitive physical or mental trauma over a period of time. California’s Division of Workers’ Compensation gives examples such as developing wrist problems from repeatedly performing the same motion or suffering hearing loss because of continual exposure to loud noise.
The injury could develop over weeks, months, or even years.
What Are Some Examples?
Cumulative trauma claims can arise in many occupations.
Examples may include:
- A warehouse employee developing chronic back pain from repeated lifting
- An office worker developing carpal tunnel symptoms from repetitive keyboard or mouse use
- A construction worker developing shoulder problems after years of overhead work
- A healthcare worker developing back or neck problems from repeatedly moving patients
- A mechanic developing hand, wrist, or elbow problems from repetitive tool use
- A factory worker experiencing hearing loss after prolonged exposure to loud machinery
- A delivery driver developing back or hip problems after years of driving, lifting, and climbing in and out of a vehicle
- A hairstylist developing shoulder or wrist problems from repetitive arm movements
California workers’ compensation guidance specifically recognizes that repeated lifting can result in progressively worsening back pain that may qualify as a cumulative injury.
Do I Need to Identify the Exact Day I Was Injured?
Not necessarily.
That is one of the major differences between a cumulative injury and a specific injury.
With a specific accident, determining the injury date may be easy.
“I fell at work on March 10.”
With cumulative trauma, there may be no single identifiable incident.
California law generally looks at when the employee first suffered disability and knew, or reasonably should have known, that the disability was caused by employment when determining the legal date of a cumulative injury.
That question can become important because the legal injury date may affect deadlines and which employer or insurance company may be responsible.
What If I Thought I Was Just Getting Older?
This happens frequently with gradual injuries.
Someone’s shoulder starts hurting and they assume it is age.
Their hands begin going numb and they think they slept wrong.
Their lower back becomes progressively worse and they assume it is simply normal soreness from working.
Then a doctor asks about their job duties and explains that years of repetitive activity may have contributed to the condition.
A worker does not necessarily have to understand immediately that their job is causing an injury.
However, once you learn or reasonably believe that your condition may be work-related, California’s Division of Workers’ Compensation advises workers to report a gradually developing injury to their employer as soon as possible.
What If I Had the Condition Before?
A pre-existing condition does not automatically prevent a workers’ compensation claim.
For example, you may have had occasional lower-back problems before beginning a physically demanding job. If repetitive work activities contributed to a new injury or worsened your condition, there may still be workers’ compensation issues to evaluate.
The medical evidence becomes particularly important in these situations.
A doctor may need to determine whether your employment caused or contributed to the condition and whether some portion of any permanent disability is attributable to other factors.
You should be truthful about previous injuries and medical treatment. Trying to hide a previous condition can create much bigger problems than acknowledging it.
How Do I Prove My Job Caused the Injury?
Because there may not be a single accident, cumulative trauma cases often depend heavily on medical evidence and an accurate description of your job duties.
Information that may become important includes:
- How long you have performed the job
- How frequently you perform repetitive activities
- How much weight you routinely lift
- How often you bend, twist, reach, push, or pull
- How much time you spend typing or performing repetitive hand movements
- What equipment or tools you use
- When symptoms first appeared
- Whether symptoms become worse while working
- Whether symptoms improve when you are away from work
- Your prior medical history
- Medical testing and physician opinions
A doctor evaluating the claim may need a clear understanding of what you actually do during a normal workday.
Saying “I work in a warehouse” provides much less information than explaining that you lift 30-pound boxes hundreds of times during an eight-hour shift.
What If My Employer Says There Was No Accident?
The absence of a single accident does not automatically defeat a California workers’ compensation claim.
Cumulative injuries are specifically recognized under California workers’ compensation law. The legal issue is whether repetitive work activities or exposures contributed to an injury that resulted in disability or a need for medical treatment.
An employer or insurance carrier may still dispute the claim.
They might argue that the condition resulted from:
- Aging
- A previous injury
- Activities outside of work
- Another job
- A medical condition unrelated to employment
Those are questions that may ultimately require medical evidence to resolve.
Should I Report a Gradual Injury?
Yes.
Once you realize or believe that your symptoms may be connected to your work, notify your employer.
The California Division of Workers’ Compensation specifically tells employees whose injuries developed gradually to report them as soon as they learn or believe the condition was caused by their job. Delayed reporting can create problems or delays in receiving benefits.
After learning about a work injury, an employer is generally required to provide or mail a workers’ compensation claim form to the employee within one working day.
Keep a copy of any claim form and other documentation you submit.
What Benefits Could Be Available?
If a cumulative trauma claim is accepted, workers’ compensation benefits may potentially include medical treatment necessary to address the work-related injury and partial replacement of wages lost while recovering.
Other benefits may become available depending on the severity and permanence of the injury. California’s workers’ compensation system does not generally provide damages for pain and suffering in the same way that a personal injury lawsuit may.
The benefits available depend on the facts of the individual claim.
What If I Worked for More Than One Employer?
Cumulative trauma cases can become particularly complicated when someone performed similar work for multiple employers.
For example, someone may have spent several years working in warehouses for different companies before developing a significant back or shoulder condition.
Determining which employer or workers’ compensation insurance carrier is legally responsible can involve specific rules governing the period during which the employee was exposed to the activities that caused the cumulative injury.
You should not necessarily assume that changing jobs means you cannot file a claim.
What If I Already Left the Job?
Leaving your employer does not automatically mean that you cannot have a cumulative trauma claim.
Some workers do not realize their condition may be occupational until after they stop performing the job.
However, post-employment claims can involve additional legal and factual issues, and deadlines still apply. California’s workers’ compensation system recognizes that a person with a cumulative injury might not realize until later that work caused or aggravated the condition.
If you believe a previous job caused an injury, it can be important to have the situation evaluated promptly.
Gradual Injuries Are Still Workplace Injuries
You do not necessarily need to fall, get hit by equipment, or experience one dramatic accident to have a workers’ compensation claim.
California law recognizes that repeatedly performing the same physical activities or experiencing the same workplace exposures can gradually cause an injury.
If your back, neck, shoulders, hands, wrists, knees, hearing, or another part of your body has progressively worsened and you believe your work contributed to the problem, consider reporting the condition, obtaining appropriate medical evaluation, and learning about your workers’ compensation rights.
A California workers’ compensation attorney can review your job duties, medical history, employment history, and symptoms to determine whether you may have a cumulative trauma claim and what steps should be taken next.
