PIAWE is calculated by taking the worker's earnings during the relevant earning period, divided by the number of weeks in the same earning period.
To calculate a worker's PIAWE, the insurer will take the worker's earnings during the relevant earning period divided by the number of weeks in the same earning period.
If a worker was working multiple jobs at the time of injury, the average weekly earnings from each job are added together to determine the worker's PIAWE.
However, each job may have a different relevant earning period depending on the specific circumstances of that job.
Short term workers (workers who have been continuously employed by the same employer for less than four weeks before the injury) may have their PIAWE calculated by considering the weekly earnings they could have expected to earn in that employment in the 52 weeks after the injury.
