What is a cumulative trauma injury in workers’ compensation?

On Behalf of | Jul 11, 2025 | Work-Related Injuries |

Cumulative trauma injuries happen when repeated stress or strain over time causes damage to your body. These injuries don’t come from a single accident. Instead, they build up slowly and often go unnoticed at first. In Illinois, workers’ compensation covers these types of injuries, just like it covers sudden accidents.

Common examples of repetitive stress injuries

Many jobs involve doing the same motion again and again. Over time, this can lead to injury. Typing all day may cause carpal tunnel syndrome. Lifting heavy boxes may lead to back or shoulder pain. Even standing on hard surfaces for long hours can damage your knees or feet.

Other common cumulative injuries include:

  • Tendonitis
  • Rotator cuff tears
  • Nerve damage
  • Hearing loss from repeated loud noise

These injuries can happen in offices, warehouses, construction sites, and even hospitals.

How Illinois workers can report and file a claim

If you think your job caused a repetitive stress injury, act quickly. In Illinois, you must report the injury to your employer within 45 days of when you first noticed it. You don’t need to know the exact day the injury started, but you should report it as soon as you connect the pain to your work.

Next, you should see a doctor and let them know the injury may relate to your job. Your doctor’s opinion will help prove your case. Then, file a claim with the Illinois Workers’ Compensation Commission. You may qualify for medical treatment, temporary disability pay, or permanent disability benefits if the injury doesn’t fully heal.

Illinois law protects workers from retaliation. Your employer can’t fire or punish you for reporting an injury.

You can protect your rights

If you suffer pain from repeated motions at work, you can speak up and protect your health and rights. If you suspect you have a work-related injury, it can be wise to take steps sooner rather than later.
