A laborer or labourer is a person who works in the construction trades, by tradition, manual labor.
Laborers are employed in the construction industry, such as road paving, building, bridges, tunnels, railway tracks. Laborers work with blasting tools, hand tools, power tools, air tools, and small heavy equipment, and act as assistants to other trades as well, such as operators or cement masons.
The 1st century BC engineer Vitruvius writes about laborer practices at that time; a good crew of laborers is just as valuable as any other aspect of construction. Other than the addition of pneumatics, laborer practices have changed little. With the advent of advanced technology and its introduction into the construction field, the laborers have been quick to include much of this technology as being laborers work.
