The prevailing wage rules apply to many different types of projects and specific jobs at those projects. What the rules do is essentially create a special, and much higher, minimum wage for certain workers on government-related projects. While it sometimes is easy to identify public works projects, other times the governmental connection can be difficult to see. It could be tax breaks, financing assistance, property grants, etc.
Employers are required to know if their contracts are subject to the prevailing wage laws. If covered, the contractor/employer must pay at least the wages set forth in the schedules.
