what is a blue collar worker

A blue-collar worker is someone who performs manual labor or skilled trades. This type of work often involves physical tasks and can be skilled or unskilled. Common industries for blue-collar workers include manufacturing, construction, maintenance, mining, agriculture, transportation, and more. The term "blue collar" originated in the 1920s, referring to the durable blue clothing—such as denim or chambray shirts—worn by these workers to hide dirt and grease during physical work. Blue-collar work usually involves tasks like building, repairing, operating machinery, and maintaining infrastructure. These workers often belong to the working class and are typically paid by the hour, unlike white-collar workers who usually work in office environments and are salaried. Examples of blue-collar jobs include factory workers, welders, electricians, carpenters, plumbers, construction workers, and maintenance technicians. While traditionally these jobs required less formal education, many now demand specialized training or apprenticeships. In summary, blue- collar workers are essential to industries that involve hands-on physical work, production, and maintenance.
