Employers conducting job analyses of physically demanding jobs can help prevent musculoskeletal injuries and control costs. Job analyses break down essential job functions into measurable physical tasks, providing a foundation for injury prevention tools like employee testing and ergonomic assessments. Injury management also uses job analysis data to help physicians determine return-to-work restrictions and develop structured work programs. Forward-thinking employers now use job analyses for fit-for-duty tests measuring an employee's ability to safely return to their usual job duties following time off for injury or illness.
