Which of the following would be considered poor ergonomic practice in maintenance?

Performing repetitive tasks without proper rest is considered poor ergonomic practice because it can lead to musculoskeletal disorders and fatigue among workers. Ergonomics emphasizes the importance of designing workspaces and tasks to fit the capabilities and limitations of employees, thereby improving productivity and reducing the risk of injury.

By neglecting to incorporate adequate rest during repetitive activities, workers are likely to experience strain and discomfort over time. This can lead to serious health issues, such as chronic pain or injuries that could have been easily mitigated with appropriate breaks. In contrast, utilizing adjustable workstations, taking regular breaks, and using lifting aids are all practices that promote better ergonomics and enable workers to operate in safer, more comfortable conditions.
