The purpose of this practice directive (PD) is to provide guidance to WorkSafeBC officers on the interpretation and application of section 218 of the Workers Compensation Act (Act) and Policy item #67.60, Exceptional Circumstances, in the Rehabilitation Services & Claims Manual (RSCM), Volume II. This PD will describe some of the situations in which it may be more appropriate to establish the worker’s long-term average earnings using this exception, rather than on the general rule in section 211.
