The 1955 system is a way of organizing workers into different jobs and pay grades. It was first introduced by Congress in 1955, and it has been used ever since in the United States. The 1955 system divides workers into six pay grades and makes sure that workers doing the same job get paid the same amount, no matter where they live or who they work for. This system helps make sure that employers can't take advantage of workers because of their race, gender, or other factors. It also helps the government set fair pay rates for different types of work.
