One of the tools a workers’ compensation insurance company has in PA to reduce, or “modify,” workers’ compensation benefits is the Labor Market Survey (LMS) (Also called “Earning Power Assessment” (EPS)). This is used when the injured worker has physical limitations which prevent a return to the injured worker’s previous occupation.
As you can see by looking at Section 123.301 in the Regulations issued by the Pennsylvania Bureau of Workers’ Compensation, before an Employer can resort to using an LMS, the Employer must demonstrate that there is no job available with the Employer within the physical limitations of the injured worker . . . or maybe not.
Recently, the Commonwealth Court of Pennsylvania decided the matter of Rosenberg v. W.C.A.B. (Pike County), which dealt with this issue. The Court held, in a narrow 4-3 decision, however, that an Employer only had to address this issue if the injured worker offered evidence (which could just be testimony of the injured worker) that a job was indeed available with the Employer. Once that evidence was presented, then the Employer had the burden of proof to show no such job existed.
