The term blue-collar refers to workers who traditionally wear blue work uniforms, including ASSEMBLY LINE and other laborers. Laborers typically wear dark-colored clothing because it does not show dirt or sweat as easily as lighter colors. Blue-collar contrasts to WHITE-COLLAR professionals, administrators, and office workers. Blue-collar is often used to describe specific locations, groups, or products. One news story described efforts to redevelop Warren, Michigan, a blue-collar city, “with its plethora of factories and industrial buildings and endless concrete ribbons that carry traffic.” Blue-collar groups are stereotypically portrayed as hard-working people with relatively little education and minimal aesthetic tastes, and blue-collar products appeal to this market segment. Blue-collar workers are more likely to be unionized and working in manufacturing rather than in service industries. A blue-collar recession would be a decline in the manufacturing sector of the economy.
