How to Report a Work Injury to Your Employer in Missouri

The metal shelf came down faster than Mike could react. One moment he was reaching for inventory at the warehouse, the next he was on the ground with sharp pain radiating through his shoulder. As he sat there trying to catch his breath, one thought pushed through the pain: what do I do now?

If you’ve been injured at work, what you do next can determine whether you get the benefits you deserve or watch your claim fall apart. Missouri law has clear rules about reporting workplace injuries, but missing a deadline or leaving out important information can put your entire workers’ compensation claim at risk.

Why Reporting Your Work Injury Matters

Under Missouri Revised Statutes Section 287.420, you need to give written notice to your employer within 30 days of your injury. Miss this deadline and you could lose your right to any workers’ compensation benefits.

When you report your injury right away, you create an official record that documents what happened while the details are fresh. This record becomes part of your workers’ compensation claim and helps prevent disputes later about whether the injury actually happened at work.

Your employer has deadlines too. They must notify their insurance carrier within five days and file a First Report of Injury with the Missouri Division of Workers’ Compensation within 30 days.

What Counts as a Work Injury in Missouri?

Not every injury that happens at work qualifies for workers’ compensation. Under Missouri law, an injury must arise out of and in the course of employment. Additionally, the accident or work activity must be the prevailing factor, meaning the primary cause, of your medical condition and any resulting disability. Each claim is evaluated based on the specific facts and medical evidence.

Injuries that commonly qualify include:

  • Slip and falls on work premises
  • Injuries from machinery or equipment
  • Repetitive stress injuries, such as carpal tunnel syndrome
  • Back injuries from lifting or other physical tasks
  • Exposure to harmful chemicals or substances

Situations that may not qualify or could reduce benefits include:

  • Injuries that occur during commuting to or from work
  • Injuries caused primarily by intoxication or drug use
  • Self-inflicted injuries or injuries resulting from horseplay that violates company policy

For occupational diseases or repetitive trauma conditions, the 30-day reporting window starts from the date of diagnosis, not when symptoms first appear. For example, if you develop carpal tunnel syndrome over several months of typing, you have 30 days from the date a doctor diagnoses the condition to report it to your employer.

Mental Injuries Face Higher Standards

Mental injuries have stricter requirements under Missouri workers’ compensation law. According to RSMo 287.120, a mental injury tied to work stress is not compensable unless the stress is proven to be extraordinary and unusual when measured by objective standards. This means the stress must exceed the level of stress that employees in similar positions typically experience. Ordinary work pressures, conflicts, or routine job duties generally do not qualify.

The law also excludes certain employment actions from coverage. Mental or emotional injuries that result from disciplinary actions, performance evaluations, job transfers, layoffs, demotions, or terminations, when these actions are taken in good faith by the employer, are not compensable under the statute.

When Do You Need to Report a Workplace Injury?

You must provide written notice to your employer within 30 days of the injury. For sudden accidents, the 30 days start from the date the injury happened. For occupational diseases or repetitive trauma, the clock starts from the diagnosis date.

The law gives you up to 30 days, but waiting almost never helps. Report your injury as soon as possible after it happens, even if you think it’s minor. Some injuries that seem small at first turn out to be more serious once you see a doctor.

There are rare exceptions to the 30-day rule. Missouri courts have said the deadline doesn’t apply if you can prove your employer wasn’t prejudiced by the late notice. This typically means the employer already knew about your injury through other means. But relying on these exceptions is risky because you have to prove the employer wasn’t harmed by the late report.

What Information Goes in Your Injury Report?

Missouri law spells out exactly what your written notice must contain. According to Section 287.420, your report must state:

  • The time of the injury
  • The place where the injury occurred
  • The nature of the injury
  • Your name and address

Being thorough pays off. For the time of injury, include the specific date and as close to the exact time as you can remember. Write “March 15, 2024, at approximately 2:30 PM” rather than “sometime in the afternoon.”

For the place of injury, provide enough detail to identify the exact location. Instead of just “warehouse,” write “west loading dock near bay door 3.”

Describe the nature of your injury clearly but don’t try to diagnose yourself. Write what you felt and observed, like “sharp pain in lower back after lifting box” or “twisted right ankle stepping off ladder.” Let the doctors determine the medical diagnosis.

How to Deliver Your Injury Report

Missouri law requires that you provide written notice of your work injury to your employer, but it does not require certified mail. Using certified mail is a recommended best practice because it provides proof of when your report was sent and received, but it is not legally mandated.

Many employers have their own accident or injury report forms. If your employer provides a form, fill it out completely and submit it. If no form is provided, you can use a generic injury report form.

How you deliver your written report is important. You can:

  • Hand-deliver it directly to your supervisor, human resources department, or another designated company representative. If you do, keep detailed records, including the date, time, full name, and job title of the person who received it.
  • Mail it to your employer. Using certified mail with return receipt requested is recommended to have proof of delivery, but regular mail is also acceptable if you can demonstrate that it was sent.

Whatever method you choose, always keep a copy for yourself. Store it safely along with any other documents related to your injury, as you may need them months or even years later.

What Happens After You Report?

Once you provide written notice of your injury, several steps should follow under Missouri workers’ compensation law:

  1. Employer reporting requirements. Your employer must report the injury to its workers’ compensation insurance carrier or third-party administrator within five days of learning about it. The insurer or administrator then has 30 days to file a First Report of Injury with the Missouri Division of Workers’ Compensation.
  2. Medical treatment arrangements. Your employer should arrange medical treatment. Under Missouri law Section 287.140, the employer or its insurer has the right to choose the authorized treating doctor or medical facility. You may choose to see your own doctor, but the employer or insurer is generally not required to pay for treatment it has not authorized.
  3. Claim investigation. The insurance company will review your injury and investigate the claim. This may include:
  • asking you questions about how the injury occurred
  • reviewing medical records
  • interviewing witnesses

You should cooperate with reasonable requests for information, but remember that the adjuster represents the insurance company.

  1. Benefits after approval. If your claim is accepted, you may receive benefits such as:
  • medical treatment for injury-related care
  • temporary total disability benefits if you cannot work for a period of time
  • temporary partial disability benefits if you return to work with reduced earnings
  • permanent disability benefits if the injury leaves lasting impairment

These benefits continue as long as they are medically and legally supported. If disputes arise, you may need to seek legal guidance or file a claim with the Division.

What If Your Employer Won’t File the Report?

Sometimes employers try to avoid filing injury reports. If your supervisor won’t file it, report the injury to someone else in authority, such as human resources, a safety officer, or upper management. Put everything in writing and keep copies of all notices and responses.

If your employer still refuses, you can file a complaint with the Missouri Division of Workers’ Compensation. You may also file a Claim for Compensation directly with the Division even if your employer has not filed its First Report of Injury.

When an employer or insurer fails to submit a required report, Missouri law extends the deadline for an injured worker to file a claim. Instead of the usual two-year limit, you may have up to three years to file under RSMo 287.430.

Mistakes That Can Hurt Your Claim

Workers make several common errors when reporting injuries.

  • Waiting too long to report is the biggest mistake. Even if your injury seems minor, report it right away.
  • Giving an incomplete report causes problems down the line. If you leave out important details about how the injury happened, insurance companies will use those gaps against you.
  • Refusing to see the employer’s chosen doctor can cost you benefits. Missouri law gives employers the right to choose your treating physician.
  • Not keeping records is something many workers regret later. Save copies of all medical records, bills, prescriptions, work restrictions, and any written communications about your injury.
  • Posting about your injury on social media can destroy your credibility. Insurance companies regularly check social media looking for evidence that contradicts injury claims. Don’t post anything about your injury, your activities, or your recovery on any social media platform.

Key Takeaways

  • Report your injury in writing to your employer within 30 days of the incident, or you could risk losing your right to workers’ compensation benefits.
  • Your written notice should include the date, time, location, nature of the injury, and your name and address.
  • Keep copies of all reports and document how and when you delivered them.
  • Your employer must notify their workers’ compensation insurance carrier within five days of learning about the injury.
  • You are entitled to medical treatment, but under RSMo 287.140, your employer or insurer has the right to choose the treating doctor or medical facility.
  • The injury must be the prevailing factor, or primary cause, of your medical condition and any resulting disability.
  • Mental or emotional injuries are compensable only if caused by extraordinary and unusual work-related stress, measured by objective standards, and not from ordinary workplace pressures or employment actions taken in good faith.

Frequently Asked Questions

Can I report my injury verbally or does it have to be in writing?

Missouri law requires written notice to your employer. While you should tell your supervisor about the injury as soon as possible, you must also submit a written report to meet the legal requirement under RSMo 287.420.

What if I reported my injury but my employer claims they never received my report?

Documentation is essential. If you have proof you submitted a report, such as a certified mail receipt or a signed acknowledgement from a supervisor, you can demonstrate that you met the reporting requirement.

My employer said the injury was my fault. Can I still file a workers’ compensation claim?

Yes. Missouri’s workers’ compensation system is generally no-fault, so you can receive benefits even if the accident was partially your fault. Benefits may be reduced or denied if the injury was caused primarily by intoxication or willful misconduct.

Can my employer fire me for reporting a work injury?

Missouri law prohibits employers from retaliating against employees for filing a workers’ compensation claim. However, an employer may terminate an employee for legitimate reasons unrelated to the injury, such as performance issues or company restructuring.

My employer doesn’t have workers’ compensation insurance. What should I do?

Missouri law generally requires most employers with five or more employees to carry workers’ compensation insurance. Construction employers must have coverage with just one employee. If your employer lacks required coverage, you may be able to file a civil lawsuit against the employer or seek benefits through the Missouri Second Injury Fund.
