"The company has built a strong customer base over decades, in part because consumers trust that it treats its workers fairly," the treasurers wrote. "A labor dispute of this magnitude risks eroding that trust, driving loyal customers to competitors and causing lasting damage to Stop & Shop's brand."

State treasurers in RI, CT and MA warn Stop & Shop of 'economic and operational consequences' amid dispute with Teamsters.

The state treasurers of Rhode Island, Massachusetts and Connecticut are urging Stop & Shop to resolve the ongoing contract dispute with the union that represents hundreds of workers at its Freetown distribution facility.

Stop & Shop — owned by the Netherlands-based Ahold Delhaize USA (OTCMKTS: ADRNY) — maintains that it has put a "fair labor savings goal" on the table that combines a "competitive healthcare plan" with a 25% increase in wages over five years.
