Which of the following is an example of an ergonomic solution?

Adjusting desk height to suit individual workers is an excellent example of an ergonomic solution because it addresses the physical comfort and efficiency of employees. Ergonomics is the study of designing and arranging workplaces, products, and systems so that they fit the people who use them. When desk heights are tailored to the individual needs of workers, it helps to promote proper posture, reduce discomfort, and minimize the risk of musculoskeletal disorders. This approach recognizes that different employees have different body types and needs, leading to improved health and productivity.

In contrast, implementing strict work boundaries, increasing work hours, and limiting employee breaks do not focus on the physical workspace or comfort of workers. These practices may even contribute to stress or discomfort, leading to decreased productivity and potential health issues. Effectively, the other options focus more on policy and management strategies rather than the human factors that ergonomics aims to optimize.
