A laborer (or labourer) is a person who works in manual labor types, especially in the construction and factory industries. Laborers are in a working class of wage-earners in which their only possession of significant material value is their labor. Industries employing laborers include building things such as roads, buildings, bridges, tunnels, and 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 that 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 introduction of field technologies, the laborers have been quick to adapt to the use of this technology as being laborers' workforce.
The following tools are considered a minimum for a laborer to keep with them: hammer, pliers w/ side-cutters, utility knife, tape measure, locking pliers, crescent wrench, screwdriver, margin trowel, carpenter's pencil or soapstone, tool belt and one pouch (bag). In addition: a five gallon bucket with additional tools, toolbelt suspenders, water jug and lunchbox are recommended.
Most safety equipment that is consumed or work specific, for example hard hat, safety glasses, hearing protection, gloves, fall protection, high-visibility clothing, concrete boots, respirator/dust mask and toe guards are provided by the employer as part of construction site safety.
Personal safety equipment, for example, full leather boots (some long-time laborers believe steel toes are dangerous on the construction site; it is better to have crushed toes than toes cut off by the crushed steel - a belief proven wrong by several studies ), high-strength pants - canvas or denim (some modify thighs with a sacrificial second layer of jean fabric cut from an old pair) - socks, lip balm, and climate-specific outerwear, are provided by the individual (unless laborers are instructed to work in a climate different from what they typically reside in, for example, high elevation).
