Are stress-related illnesses covered by workers’ comp?

On Behalf of | Jun 23, 2026 | Workers' Compensation

Workplace stress can lead to more than frustration or burnout. In some cases, it can cause conditions that affect your ability to work and manage daily life. When this happens, you might be wondering if workers’ compensation covers these types of injuries.

Coverage for stress-related conditions

Under California law, a mental health injury may be covered by workers’ comp if it results in a mental disorder that causes disability or calls for medical treatment. This includes conditions such as clinical depression, anxiety disorders, post-traumatic stress disorder and adjustment disorders predominantly caused by your employment.

The law draws a line between two types of claims. A “physical-mental” claim involves a mental health condition that develops after a physical work injury, while a “mental-mental” claim involves an illness where workplace stress or trauma is the predominant cause of the injury.

Standards for a compensable claim

To pursue a stress-related claim, you must meet several requirements that do not apply to most physical injury cases. A licensed psychiatrist or psychologist needs to diagnose you using criteria from recognized diagnostic standards, and it must cause disability or require treatment.

You must also show that the events of your job were the primary cause of your condition. Under state law, this means work must account for more than 50% of the cause. A lower bar applies if you were the victim of workplace violence or saw a violent act firsthand, where 35% to 40% is enough.

In most cases, you must have worked for the same employer for at least six months — though this time does not need to be continuous — before the illness developed. This does not apply if a sudden and extraordinary employment circumstance caused the injury.

Obstacles in the review process

Even when you feel certain the job caused the harm, a few points in the process tend to draw scrutiny. The following can affect how the process unfolds:

  • Showing the job was the main driver of your stress, rather than just one of several contributing personal factors
  • Overcoming an employer’s claim that your stress stemmed from a lawful, good faith personnel action
  • Meeting the length-of-employment rule without a qualifying sudden event
  • Securing clear medical records that explicitly link the diagnosis to your workplace

These factors do not mean a stress claim cannot succeed, but they do highlight the value of early planning.

Support for a stronger case

A stress-related claim often turns on detail, including the timing of events, the wording of a diagnosis and how work compares to everything else in your life. Building a record that speaks to those points tends to matter more here than in a routine physical claim.

An attorney can also work with your medical providers so that your records clearly reflect the tie between your condition and your job. When a claims handler disputes the cause, solid and steady records from the start can make a meaningful difference in the outcome.
