A functional job assessment (FJA) is a systematic procedure to quantify and evaluate the physical, cognitive, and environmental demands of the essential and non-essential tasks of a job. The presenter discusses how employers can use FJAs reactively for rehabilitation and return to work. He also explains how these actions can prevent injury. The presentation also includes how to communicate the requirements of a job to associates and health-care providers, provide data for use in job matching and accommodation for injured workers, identify suitable alternate work or modified work and assist in identification of jobs, work processes and equipment that require further evaluation.
