Why Join a Union?


The United Association of Boston Pipefitters Local Union 537 was issued its original Charter in 1911. Local Union 537 members are direct descendants of the original Steam Fitters Union organized in the late 1870’s. The 1870’s and 1880’s marked the beginning of a boom in development and high prosperity.  Local Building Trades Unions were established to protect tradesmen during this time of high demand for skilled labor. Unions of all different professions, not just Building Trades Unions, have been accredited to being a major component in the development of the middle class. All sectors of the working class benefit from the 40 hour work week and paid overtime that our forefathers fought for. All sectors benefit from the minimum wage standards, paid holidays, sick time, maternity leave, employee rights, safety and construction standards. Our Union is fighting for the same issues our Union Brothers and Sisters strived for 100 years ago; building, renovating, and servicing in a way that is beneficial to corporate America, the community, and the working men and women.

Unions create a safe working environment for the worker as well as the people who ultimately wind up utilizing the facilities that are being built, renovated, or serviced.  While doing so, Unions secure a beneficial wage structure for the Tradespersons and Professionals alike

The New England Mechanical Contractors Association (NEMCA) joins in our effort for safety and quality control, and most importantly; care about the people they employ. Apart from our non-union competitors, NEMCA and Local 537 members negotiate a personal benefits package in the form of employee healthcare, annuity, pension plans and education. These benefits accumulate for each member individually over the years, from contractor to contractor, ensuring our members can retire with dignity by investing their own money, toward their future and financial security.

Our Brotherhood has a five year apprenticeship program prior to reaching journeyman and journeywoman status. Each apprentice trains in our state of the art training facility along with being mentored in the field. Boston Pipefitters Local Union 537 trains apprentices in the field during the day and are classroom educated in simulated working environments at our school in the evening. We are all extremely dedicated to our craft.  Local 537 Journeymen and women go beyond industry standards training themselves to be aware of all industry standards and requirements.

Union membership is a gateway for many to join the Middle Class; Hard working, dedicated men and women who take pride in our trade and our communities are members of Pipefitters Local 537. A “Brotherhood” that unites together as one, so each individual has the same opportunities and a chance for a better future.
