This is essential. Ergonomic re-design, however, will not correct all of the problems. Faulty work design may not even be the problem.

Workers simply swap jobs occasionally during the work day to gain a variety of work demands.
Frequently switching between sitting and standing where practical is another form of task rotation. Work task or posture variety spreads work demands over more musculoskeletal tissues, reducing the net stress to any specific structure. Another highly effective low-cost option is preventive stretching. Some experts hesitate to recommend exercises because they fear they will be ineffective or even unsafe. Preventive stretching exercises must meet certain prerequisites to be safe and effective.
