When a worker gets hurt, understanding whether the injury qualifies as a work injury under workers’ compensation laws is critical. This determines not only eligibility for medical treatment and wage replacement, but also whether an employer’s insurer must pay benefits. Many workers assume that any injury that happens “at work” qualifies, but that’s not always true. 

The key legal rule in most systems, like U.S. state workers’ compensation programs, is that an injury must both arise out of and occur in the course of employment. In practical terms, this means the injury must be connected to job duties or the work environment in a way that is more than incidental or coincidental.

What Counts as a Work Injury

A work injury is an accidental injury or occupational disease directly linked to job duties or conditions. This includes typical on-the-job accidents such as a construction worker falling off scaffolding, a factory employee’s hand caught in a machine, or a delivery driver injured in a traffic collision while making deliveries. 

It also includes injuries from repetitive stress that develop over time from required work tasks, like carpal tunnel syndrome from repeated keyboard use, if it can be shown that the work significantly contributed to the condition.

When evaluating these injuries, a work injury lawyer often looks for evidence that the work activity was a major contributing factor to the harm rather than a minor or incidental one. That standard helps separate genuine work injuries from injuries that would have occurred regardless of employment. Examples of qualifying work injuries:

• A warehouse worker sprains their back lifting a heavy pallet as part of their job.
• A nurse contracts a recognized occupational disease, like a respiratory infection, after repeated exposure to sick patients.
• A delivery driver is injured in a traffic accident while performing scheduled work deliveries.

In 2023, there were about 2.8 million nonfatal workplace injuries and illnesses involving days away from work in private industry, illustrating how frequent work injuries are in varied job settings.

What Doesn’t Count as a Work Injury

Not all injuries that happen “around work” are compensable. Many claims are denied because the injury does not meet both parts of the legal test. Injuries typically not considered work injuries include:

• Personal errands or breaks: If a worker is on an extended lunch break or runs a personal errand unrelated to job requirements and is injured, this is usually not compensable.
• Pre-existing conditions unrelated to work: An old injury that flares up outside of work and without clear contribution from work duties.
• Injuries from intentional misconduct: If a worker is injured while intentionally harming themselves or engaging in deliberate misconduct unrelated to job tasks, they may deny your claim.
• Injuries that occur outside the course of employment: For example, a worker slips and falls in the parking lot before clocking in when there’s no evidence that the work premises or job duties contributed to the fall.

A helpful rule of thumb is that the injury must be something the worker would not have suffered “but for” the work or the work environment. If the same event had occurred regardless of where the person was or what they were doing, it likely would not qualify.

Special Situations to Understand

There are some gray areas that deserve specific attention:

• Travel-related injuries: Injuries during required business travel often qualify, but injuries during ordinary commuting to and from work usually do not. Some jurisdictions recognize “special mission” exceptions when travel is part of a worker’s job duties.
• Repetitive stress injuries: These are injuries that develop over time from the nature of the job. This category often triggers disputes because insurers may argue the condition is a “personal risk.” Documentation from a medical provider tying the injury directly to work activities is essential.
• Mental injury: Psychological injuries can be compensable if caused by a specific work event or occupational exposure and supported by medical evidence.

What Workers Should Do

If a worker is injured and believes it may be work-related:

• Report it immediately to the employer in writing.
• Seek medical evaluation from an appropriate provider and document all details.
• Document how the injury happened, what work tasks contributed, and any witnesses.
• Keep copies of all forms and medical records.
