"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, road paving, buildings,
bridges, tunnels, pipelines civil
and industrial, and railway tracks.
Laborers work with blasting tools, hand
tools, power
tools, air
tools,
and small heavy
equipment,
and act as assistants to tradesmen
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"
