(WCB) Minimal conditions that must be met before financial responsibility can be assigned to a claim for workers’ compensation based on occupational disease. Specifically, it must be established that (a) the claimant has an occupational disease recognized by the WCL, (b) the claimant has, after the onset of the disease, notified his/her employer within the statutory time limit (two years from date of disablement or from date when claimant knew or should have known that the disease was due to the nature of the employment, whichever is greater), and (c) a causal relationship exists between work-related activities and exposure, the development of the occupational disease, and a subsequent disability.
