An Act relative to the protection of small businesses and workers

HD 4047, titled "An Act relative to the protection of small businesses and workers," establishes new antitrust rules targeting monopolies and monopsonies in Massachusetts. It defines "monopoly power" (controlling prices or excluding competition) and "monopsony" (a single buyer dominating a market), making contracts that create or maintain such power unlawful. The bill presumes dominance if a business holds 40%+ of a product market or 30%+ of a labor market, and prohibits abuses like wage suppression, anti-union restraints, or forcing exclusive deals. It directly affects large businesses or employers with dominant market positions, aiming to protect small competitors and workers' bargaining power.
