Ergonomics is defined as the science of fitting jobs to people. It aims to optimize the relationship between workers and their jobs by developing workplaces and tools that minimize physical and mental strain. The objectives of ergonomics include improving productivity and accuracy by optimizing human-machine integration, developing workplaces tailored to workers' needs, and arranging tools to reduce fatigue and injury risks. Advantages of ergonomics include higher productivity, increased safety, reduced employee turnover, and better employee satisfaction through making work easier and more comfortable.
