Public Works

Public work, or work that is contracted out by a public entity such as a county or the federal government, must be paid at the prevailing wage. Work in this context includes construction, alterations, repairs or improvements funded by a county or other public agency. There is no national prevailing wage, as the wage is determined by the average wage that employers pay to the majority of individuals in a particular job category within a specific geographic location.

Prevailing wages can vary by state or county, and also according to the actual job.

In states with a strong union presence, the prevailing wage is often the union wage, according to the Laborers International Union of North America.
