Cumulative Trauma Injuries: You Can Still File After Leaving the Job

A common misconception is that you have to still be working for an employer to file a workers' compensation claim connected to that job. For cumulative trauma injuries — conditions that build up gradually from repeated work activity — that's often not true.

What Counts as Cumulative Trauma

California Labor Code § 3208.1 defines a cumulative injury as one resulting from repetitive physical or mentally traumatic activities extending over time, where the combined effect causes disability or the need for treatment. Carpal tunnel syndrome from years of repetitive hand motion, degenerative back or joint conditions from physical labor, and hearing loss from prolonged noise exposure are common examples.

Why the Filing Deadline Is Different

For a sudden, specific-incident injury, the clock generally starts on the date of the accident. For a cumulative injury, it generally starts when you knew, or reasonably should have known, that the condition was both disabling and work-related — which can be well after you've changed jobs or left the workforce for the condition.

What This Means in Practice

• You don't need to still be employed at the company where the repetitive activity occurred to file
• Multiple employers over the relevant period can, in some cases, share liability for a single cumulative injury
• A diagnosis alone doesn't automatically start the clock — it's tied to knowing the condition is both disabling and work-connected

Why These Claims Get Disputed

Insurers frequently push back on cumulative trauma claims by pointing to age, a hobby, a different job, or general "wear and tear" as the real cause rather than this specific employment. A detailed work history — specific tasks, frequency, duration, and how the condition developed — is usually the deciding factor in these disputes.

The Takeaway

If you have a condition that developed gradually from years of repetitive work — even if you've since changed jobs or retired — it's worth having the timing and the facts reviewed rather than assuming it's too late. These deadlines are specific, not automatic, and they often work differently than people expect.
