MASON TENDERS’
DISTRICT COUNCIL

The Mason Tenders’ District Council of Greater New York and Long Island has emerged as one of the most progressive and aggressive labor organizations in the nation. The over 17,000 members of the Mason Tenders District Council (MTDC) include construction workers, asbestos and hazardous materials handlers, Catholic High School teachers, recycling and waste handlers.

Laborers are the backbone of the construction industry. Working alongside other construction tradespeople, Laborers perform many different tasks on a construction site.
