the.com/collective bargaining

means The process by which a group of workers, through their union, negotiates as one voice with an employer over wages, hours, and working conditions instead of each person bargaining alone.

from The term was coined in the late 1800s by Sidney and Beatrice Webb, British social reformers who studied labor movements and needed a name for what unions actually did at the negotiating table — 'collective' from Latin collectivus, 'gathered together,' plus 'bargaining,' from an Old French word for haggling over a deal. The Webbs popularized the phrase in their writings on trade unionism, and it stuck because it named something real: a shift from individual pleading to organized leverage.
