Stress Leave: California Workers’ Compensation Guide

Feeling mentally exhausted by work? You’re not alone. California law recognizes that severe workplace stress can cause legitimate, compensable injuries — but navigating a psychiatric or stress-related claim is uniquely challenging. Below is the Employees First Labor Law (EFLL) playbook for understanding, filing, and winning stress-leave workers’ comp cases in 2025.


1. What Counts as “Stress Leave” Under Workers’ Comp?

“Stress leave” refers to time off work taken because psychological or emotional strain has become a disabling condition. In the comp system this is called a psychiatric injury (Cal. Lab. Code § 3208.3). To qualify, the mental condition must:

  1. Be diagnosed by a licensed physician or psychologist under DSM-5 criteria.
  2. Cause disability or need for medical treatment.
  3. Be at least 51 % caused by actual events of employment (the “predominant cause” test).
  4. Result from events of employment lasting six months or more (unless it’s a “sudden and extraordinary” event like a violent robbery).

Example: A call-center rep develops debilitating anxiety after 14 months of constant verbal abuse from customers and unrealistic performance metrics.


2. Common Work Stressors That Trigger Claims

  • Excessive workload & understaffing
  • Bullying, harassment, or discrimination
  • Witnessing workplace violence or traumatic accidents
  • Unfair discipline or demotion
  • Fear of retaliation for whistleblowing or reporting safety issues

3. How to File a Stress-Related Claim

5. Employer & Insurance Company Defenses (and How We Counter Them)

DefenseCarrier’s PlaybookEFLL Counter-Strategy
“Good-Faith Personnel Action”Discipline, demotion, or transfer was lawful, so no comp liability.Show that action was retaliatory, excessive, or not the predominant cause.
“Predominant Cause Not Work-Related”Blame divorce, finances, or prior mental illness.Obtain treating-doctor opinion, subpoena therapy records only if helpful, produce co-worker statements.
“Late Filing”Claim wasn’t reported within 30 days.Use cumulative-trauma theory; argue ignorance of psychiatric nature delayed reporting.

6. Tips to Strengthen Your Stress-Leave Case

  1. Document Everything — objective proof beats “he-said-she-said.”
  2. Follow Medical Advice — gaps in treatment weaken credibility.
  3. Avoid Social Media Missteps — photos of vacations or parties can be twisted against you.
  4. Stay Consistent — your story to HR, doctors, and the insurer must align.
  5. Retain Experienced Counsel Early — psychiatric claims are denied far more often than physical-injury claims.
