Ergonomics is the science of designing work processes and equipment in a workstation to make employees comfortable and increase their productivity. Ergonomics is important because when you're at work and your body is in stressful situations like improper posture, extreme temperature, or repeated movements,  your musculoskeletal system is affected which results in lower productivity.

Sitting in the same position for long periods of time and squinting are not good ergonomic practices. Sam using a power screwdriver to avoid repetitive motions is a good ergonomic practice.
