Some examples of white-collar jobs are computer programmer, certified public accountant, human resources manager, administrative assistant and newspaper reporter. White-collar workers are usually office workers.
The terms white-collar and blue-collar became popular in the 1920s. White-collar workers are professionals and usually work in office buildings or the clergy. Their jobs do not involve much, if any, manual labor, and they do not wear uniforms.
Blue-collar workers, by contrast, usually have intense physical labor jobs. They wear uniforms to work and often work outdoors, perform civil service or work in restaurants or retail stores. Examples of blue-collar jobs include police officers, construction workers, sales associates, restaurant cooks and landscapers.
