A blue-collar worker is a working class person who performs manual labor or skilled trades. Blue-collar work may involve skilled or unskilled labor. The type of work may involve manufacturing, warehousing, mining, excavation, carpentry, electricity generation and power plant operations, electrical construction and maintenance, custodial work, farming, commercial fishing, logging, landscaping, pest control, food processing, oil field work, waste collection and disposal, recycling, construction, maintenance, shipping, driving, trucking, and many other types of physical work.[excessive detail?] Blue-collar work often involves something being physically built or maintained.
In contrast, the white-collar worker typically performs work in an office environment and may involve sitting at a computer or desk. A third type of work is a service worker (pink collar) whose labor is related to customer interaction, entertainment, sales or other service-oriented work. Particularly those service jobs that have historically been female dominated such as nurses, teachers, early childhood educators, florists, etc.[1] Many occupations blend blue, white, or pink-collar work and are often paid hourly wage-labor, although some professionals may be paid by the project or salaried. There are a wide range of payscales for such work depending upon field of specialty and experience.
