ErgoX: Job Rotation: Assessment of Current Practices for Musculoskeletal Disorder Risk using Fatigue Failure Tools
DescriptionThe practice of rotating employees through different workstations/jobs within a given time frame (e.g., one work shift) is neither new nor rare in the manufacturing industry. Job rotation is used to increase the production skillset of employees to provide employment/staffing flexibility in the production process. From a musculoskeletal disorder risk perspective, the objective is to reduce repetitive exposure and accumulated biomechanical loading to specific body parts. The effectiveness of a job rotation scheme depends in part on how well biomechanical stress is minimized across numerous body parts. An optimal (balanced) job rotation scheme would minimize the biomechanical stress on each of the body regions by ensuring that the jobs in the rotation scheme alternate the physical demands on the body. Quantifying actual exposure would provide valuable information on whether existing job rotation schemes adequately balance WMSD risk factor exposures and the ability of these schemes to control WMSDs.
