Cal. Lab. Code § 3600
(a) Liability for the compensation provided by this division, in lieu of any other liability whatsoever to any person except as otherwise specifically provided in Sections 3602, 3706, and 4558, shall, without regard to negligence, exist against an employer for any injury sustained by his or her employees arising out of and in the course of the employment and for the death of any employee if the injury proximately causes death, in those cases where the following conditions of compensation concur:
(10) Except for psychiatric injuries governed by subdivision (e) of Section 3208.3, where the claim for compensation is filed after notice of termination or layoff, including voluntary layoff, and the claim is for an injury occurring prior to the time of notice of termination or layoff, no compensation shall be paid unless the employee demonstrates by a preponderance of the evidence that one or more of the following conditions apply:
(D) The date of injury, as specified in Section 5412, is subsequent to the date of the notice of termination or layoff.
For purposes of this paragraph, an employee provided notice pursuant to Sections 44948.5, 44949, 44951, 44955, 72411, 87740, and 87743 of the Education Code shall be considered to have been provided a notice of termination or layoff only upon a district’s final decision not to reemploy that person.
A notice of termination or layoff that is not followed within 60 days by that termination or layoff shall not be subject to the provisions of this paragraph, and this paragraph shall not apply until receipt of a later notice of termination or layoff. The issuance of frequent notices of termination or layoff to an employee shall be considered a bad faith personnel action and shall make this paragraph inapplicable to the employee.
