The calculation of the Average Weekly Wage (AWW) under the Pennsylvania Workers’ Compensation Act has been explained previously on this blog. Generally, assuming the injured worker had been working for his or her employer for more than a year before the work injury, the AWW is calculated by taking the average earnings of the injured worker for the highest three quarters in the year immediately before the injury.
Occasionally, we have a question regarding whether the injured worker has been “employed” for more than a year before the injury, perhaps due to layoffs. The Supreme Court of Pennsylvania Courts told us in 2005, in Reifsnyder v. Workers’ Compensation Appeal Board (Dana Corp), that despite periods of layoff, the term of “employment” continued. In that matter, Mr. Reifsnyder was considered to have zero earnings for the weeks he was laid off, for the purposes of calculating his AWW.
Also in 2005, the Supreme Court of Pennsylvania told us, in Colpetzer v. Workers’ Compensation Appeal Board (Standard Steel), that when an injured worker is disabled by a work injury in the one year period prior to another work injury, the AWW for the subsequent injury should include the AWW from the previous injury for any periods the worker was disabled by the previous injury.
