How can job rotation reduce ergonomic risk?

Job rotation can significantly reduce ergonomic risk primarily by minimizing repetitive tasks and the associated strain on specific body areas. When employees are allowed to rotate through different tasks, they are less likely to engage in the same motions or postures for extended periods. This variety helps to alleviate the stress placed on particular muscles and joints, which can lead to discomfort or injury over time.

By distributing the workload across different tasks, job rotation reduces the likelihood of repetitive strain injuries. Employees who switch tasks within their designated work periods experience a more balanced use of their muscle groups, thus reducing fatigue and the potential for musculoskeletal disorders. This is especially critical in ergonomics, where repetitive motion is a significant risk factor for injury.

The other options do not effectively align with the principles of ergonomics. For instance, increasing workload or promoting longer hours at the same workstation could exacerbate strain and fatigue, while eliminating breaks does not contribute to recovery, which is essential for maintaining workplace health and comfort.
