Mason Tender District Council

What Mason Tender District Council does

The Mason Tenders' District Council of Greater New York and Long Island is a labor union district council affiliated with the Laborers' International Union of North America (LIUNA), representing over 17,000 members across five chartered local unions. Its membership spans construction workers, asbestos and hazardous materials handlers, recycling and waste handlers, and Catholic high school teachers, with Local 79 (10,000+ members) being the largest Laborers' Local in the United States and Local 78 performing approximately 90% of all asbestos removal in the NYC, Long Island, and New Jersey area through roughly 200 signatory environmental contractors. The council's core function is collective bargaining with approximately 1,500 signatory construction and environmental contractors, supported by an integrated service ecosystem that includes the Mason Tenders Training Fund (60+ courses in English, Spanish, and Polish), MTDC Trust Funds administering health, welfare, pension, and annuity benefits, the MTDC Political Action Committee for government and regulatory advocacy, and Tenders Inc., a 501(c)(3) charitable foundation.

The organization operates as a non-profit member-funded entity with no public revenue disclosure, generating operating income through member dues and affiliated program activity. Its geographic footprint covers New York City (five boroughs), Long Island (Nassau and Suffolk Counties), Westchester, Hudson Valley, New Jersey, and the Danbury area of Connecticut. Distribution is handled through the five local union offices (Locals 66, 78, 79, 108, and 1261), training facilities operated by MTTF, and trust fund offices across the region. The council was established in 1955, though constituent locals date back to 1932 (Local 66) and 1937 (Local 108), with significant consolidation activity in 1996 forming Local 79 and additional structural moves through 2007.

Revenue mechanics are anchored on recurring member dues, employer benefit contributions flowing through trust fund structures, training fund fees, PAC contributions, and LECET joint labor-management program budgets. There is no traditional GTM motion or pricing model; growth and retention depend on collective bargaining coverage, political advocacy that has influenced tens of billions of dollars of unionized construction work since 1998, and the integrated benefits/training ecosystem that binds members and contractors into long-tenure relationships. The current executive leadership includes Business Manager David Bolger, President Pawel Gruchacz (Local 78), Vice President John Norbury (Local 79), and Secretary-Treasurer Anthony Vita, with Tamir Rosenblum serving as General Counsel and Lorraine Tavarez as Director of Finance.
