Massachusetts prevailing wage laws require employees on public works projects be paid a minimum hourly rate set by the Department of Labor Standards. The prevailing wage laws apply to both union and non-union employers and employees. Prevailing wages must be paid to covered workers on public works projects, whether they are employed by the general contractor, a filed sub-bidder, or any sub-contractor. These laws are enforced by the  Attorney General's Office. Please see more information about Prevailing Wages here
