Employers facing an emotional distress claim often lead with workers' comp exclusivity. In California demurrer rulings on IIED claims pled alongside an employment claim, exclusivity was the court's stated reason in 4 of the 44 knockouts we could check. It was the reason in none of the 9 claims that died for good.
The rule
Workers' compensation exclusivity (Labor Code § 3600 et seq.) bars an IIED claim when the underlying conduct is ordinary employment friction, such as a personnel decision or a management dispute. Livitsanos v. Superior Court, 2 Cal.4th 744 (1992) and Accardi v. Superior Court, 17 Cal.App.4th 341 (1993) state the rule directly: exclusivity does not bar a suit for emotional distress damages attributed to unlawful discrimination, harassment, or other misconduct that, as Livitsanos put it, "exceeded the normal risks of the employment relationship."
The number
Of 73 decided IIED claims pled alongside an employment claim, the demurrer was overruled in 25, sustained with leave to amend (or leave not stated) in 37, and sustained without leave in 11, as of October 21, 2026.
What decides it: the reasons courts gave
We could check the court's stated reason, word for word, in 44 of the 48 knockouts, including 9 of the 11 that died for good.
| Why the claim was knocked out | Knockouts | Of those, died for good |
|---|---|---|
| Conduct not extreme and outrageous | 16 of 44 | 3 |
| Ordinary personnel decisions | 9 of 44 | 2 |
| Labels instead of facts | 5 of 44 | 0 |
| Workers' comp exclusivity | 4 of 44 | 0 |
| No facts showing severe emotional distress | 2 of 44 | 0 |
| Filed after the two-year limitations period | 2 of 44 | 1 |
| Conduct not aimed at the plaintiff | 1 of 44 | 1 |
| Fell with a failed claim it depended on | 1 of 44 | 0 |
| No statutory basis against a public entity | 1 of 44 | 0 |
| Other: a missed government claim, a plaintiff who did not oppose, and a complaint that never identified the conduct | 3 of 44 | 2 |
| Total | 44 | 9 |
The first three rows, 30 of 44, are the outrageousness fight. Personnel decisions lose on their own terms: "A simple pleading of personnel management activity is insufficient to support a claim of intentional infliction of emotional distress, even if improper motivation is alleged." (Los Angeles, 25STCV10579, 2026-06-03.)
When exclusivity did win, the complaint described ordinary work conditions. "All of the Complaint’s allegations relate to the operation of Omnitrans’ business and either Plaintiff’s employment (i.e., his termination) or the conditions of his employment which are subject to worker’s compensation exclusivity." (San Bernardino, CIVRS2510110, 2026-05-25.)
What the average hides: exclusivity against harassment
When the employer raised exclusivity against an IIED claim built on harassment or discrimination, the demurrer was overruled in both rulings we found. One court said: "it is settled under California law that employees may pursue claims for IIED so long as such claims are based on conduct which also violated FEHA." (Los Angeles, 26STCV02709, 2026-06-10.) Two rulings is an example, not a pattern.
One ruling went the other way, and it shows where the line is. The coworkers' comments there were tied to the plaintiff's work: "While the alleged comments by coworkers were potentially harassing based on a protected characteristic as discussed above, they did relate to Plaintiff’s work practices and are thus covered under worker’s compensation exclusivity." (Los Angeles, 26STCV08427, 2026-06-15.)
What to do
| If you represent the employer | If you represent the employee |
|---|---|
| Plead exclusivity, since it costs nothing to preserve, but don't build the demurrer around it. It was the reason in 4 of 44 knockouts. | Plead the conduct as discrimination or harassment if that is what it was. Exclusivity lost both times it was raised against that kind of claim. |
| Attack outrageousness instead. Is the conduct specific and repeated, or a personnel decision with a harassment label? | Don't rest on "hostile work environment." Plead what was said or done, by whom, and how often. |
Method: 333 IIED claims in 326 California superior court tentative rulings on demurrers. 74 were pled alongside an employment claim, and 73 of those were decided, as of October 21, 2026. Reasons are LawSnap's coding of the court's main stated reason, one per claim, checked word for word against the ruling, for 44 of the 48 knockouts and 22 of the 25 survivals. Claims pled alongside both an employment and a habitability claim are a separate group and are left out. The workers'-comp rule cites published California authority (Livitsanos v. Superior Court; Accardi v. Superior Court). These are tentative rulings, not precedent, and these counts are not odds of winning. Nothing here is legal advice.
