The Building & Construction Trades Council of the Metropolitan District represents 35,000 working families in the Metropolitan Boston region. The building trades unions advance social and economic justice by providing family-supporting wages, healthcare benefits and dignified retirement benefits to workers and their families in the construction industry.

The Building and Construction Trades Council, an umbrella group of 20 local construction unions, in partnership with more than 3,300 union contractors, provides the highest standards for workers in the construction industry. It is through collective bargaining and the Labor-Management partnership that workers achieve the highest levels of training, safety and economic security throughout their careers.

The Council strives to create a more fair and just environment for all workers in the construction industry.
