A project employment contract (PLA) is a pre-employment collective agreement that sets out the terms and conditions of employment for one or more construction projects. THE PLAs were first used in major public works projects in the 1930s, such as the Hoover Dam. Since then, many large complex projects, both public and private, have been successfully built in the United States with the PLA model, such as Kitsap Naval Base, Cove Point – LNG Export Terminal, LAX AIRPORT, the replacement Zee Bridge tappan and each of Toyota Motor Corporation`s North American production sites. Through the Walt Disney World office in Florida, Construction Unions in North America are working with Disney Corporation to negotiate collective agreements that allow for the development of school programs while ensuring that new construction projects and ongoing maintenance at Walt Disney World are carried out safely and efficiently. , with wages and family benefits. The method uses the well-structured and effective training programmes of the craftsmen`s union, developed at the national level by training trade union organisations and made available to local training centres for implementation. The NMAP, developed by a tripartite committee made up of representatives of international trade unions, national maintenance operators and procurement representatives, takes into account the knowledge and experience gained through union learning programmes and provides evidence of basic knowledge and skills. The national construction agreement aims to promote the efficiency of all work; ensure a peaceful resolution of artisanal disputes without strikes or lockouts; and promote the timely and cost-effective completion of the project.

The department has had contractual relationships with VAT for nearly 60 years through the Tennessee Valley Trades and Labor Council. During this period, VAT`s construction and maintenance needs created thousands of jobs for artisanal businesses and kept supply rates low to benefit all the inhabitants of the valley. Through a committee set up by the 14 general presidents, North American construction unions are working with unionized contractors to secure jobs as contractors across the country.
