What Transport Workers Union Local 100 does
Transport Workers Union Local 100 is a labor union founded in 1934 by Michael J. Quill, headquartered at 195 Montague Street in Brooklyn, New York, and affiliated with the Transport Workers Union (TWU) International based in Baltimore. It represents approximately 36,000 transit workers across multiple divisions, including Rapid Transit Operations, TA Surface, MTA Bus, MaBSTOA, Maintenance of Way, Stations, and Car Equipment, employed by the New York City Transit Authority, MTA Bus Company, and the Manhattan and Bronx Surface Transit Operating Authority. The union is a private, nonprofit labor organization; it does not sell products or services and does not develop proprietary technology, operating instead as a member-funded advocacy and representation body. Its primary product offering is collective bargaining representation, grievance handling, and workplace safety advocacy, supplemented by an integrated member-benefits stack including a childcare fund, training and upgrading fund, housing assistance, union scholarships, widows and orphans support, a union assistance program, and coordination of medical, prescription, vision, dental, and hearing benefits through third-party administrators.
Revenue is generated almost exclusively through member dues collected as a recurring subscription against MTA payroll, with no other diversified income stream of comparable scale. The union's go-to-market model is community-led workplace organizing: representatives recruit and retain members directly at transit depots, stations, and maintenance facilities, then deliver representation, benefits administration, political advocacy, and community engagement (e.g., Pride, Juneteenth, labor-day actions) as bundled member value. Operationally, the union is governed by elected officers including President John V. Chiarello, Administrative Vice President Alexander Kemp, and Secretary-Treasurer Earl Phillips, with divisional Vice Presidents embedded in each MTA worksite. Its competitive position rests on legally protected exclusive representation rights within its certified bargaining units, a multi-decade brand and organizing infrastructure, and an established track record of contract wins, including the 1966 strike that overturned the Condon-Wadlin Act.
