Local 537 is excited to celebrate Red Sox’s opening day with our Greater Boston and New England communities! On this day, we honor the legacy that building trades unions have established in this country, including Fenway Park’s union-built legacy since 1912. As the oldest and most renowned stadium in Major League Baseball (MLB), the construction of Fenway Park is a historic milestone for building trades unions.

Our union roots are strong and we are proud to celebrate the Red Sox’s opening day, and all of the great union accomplishments that have strengthened Major League Baseball as a whole.

Go Sox!
