Labor Code Section 5412
The date of injury in cases of occupational diseases or cumulative injuries is that date upon which the employee first suffered disability therefrom and either knew, or in the exercise of reasonable diligence should have known, that such disability was caused by his present or prior employment.
The Section 5412 date of injury is the date the employee first suffered disability and knew or should have known it was work-related; this date must be established to determine liability.
From the decision · page 4Pursuant to Section 5412:

(Lab. Code, § 5412.)
As noted above, at the trial the parties stipulated that applicant's period of employment for
Atkore International was during the period from November 2013, through January 2019. In order
to determine the section 5412 date of injury, the date that applicant first suffered disability and
knew that the disability was caused by his employment, must be established. Our review of the
record indicates these dates have not been adequately established.
