Ergonomics is the science of designing the job to fit the worker, rather than physically forcing the worker's body to fit the job.

Ergonomics deals with the interaction of technological and work situations with the human being. Ergonomists use anatomy, physiology and psychology to identify the most productive use of human capabilities, and to then maintain human health and well-being by making sure that jobs fit the person or people who perform them. This requires taking into account differences such as size, strength and ability to handle information for a wide range of users and then designing tasks, work spaces and tools around those differences. The benefits of ergonomics include improved efficiency, quality and job satisfaction, as well as a reduced risk of fatigue, strain and job-related injury.
