In the last few years we have seen a substantial increase in the number of cases of REL/WMSD (Repetitive Effort Lesions/ WMSD(Work-Related Musculoskeletal Disorders) in Brazil and in the world, raising a relevant concern on the part of various segments of society, which have tried to learn more and find solutions for these occupational disorders. REL / WMSD disorders are nowadays the main cause of leave from work due to medical reasons and are responsible for considerable financial losses for companies, businessmen and the public treasury, as well as considerable suffering for workers. Those disorders have also formed the base of union claims and compensation claims made by employees against companies. Ergonomics are fundamental to the analysis of activity and the development of furniture and equipment for workstations, presenting solutions to lighten the physical, cognitive, and emotional overload of employees.The setting and furniture that have undergone correct ergonomic treatment, and are used in accordance with guidance, bring comfort and security to users, who can then devote themselves longer and more productively to their professional activities. This results in immediate benefits to employees and the company that invested proactively in health. The saying: "Better safe than sorry" is therefore quite worth quoting there and Ergonomics is the key to success. Dra.
