This article conceptualises a model for rectifying what little is known about the joint distribution and health effects of physical and psychosocial hazards (e.g., noise, dusts, fumes, and job strain) and social hazards (e.g., racial discrimination and gender harassment) encountered at work. It describes recruitment strategies and the characteristics of study participants in the United for Health study. This study recruited 14 worksites from the areas of manufacturing, meat processing, retail, and transportation, and 1282 workers, of whom 62% were men, 36% were women, 39% were Black, 23% were Hispanic, 25% were White, 31% earned less than a living wage, 40% were below the poverty level, and 23% had less than a high school education.
