General laborers do not need any special training to work in construction. The training happens as laborers work under skilled tradesmen, such as masons, carpenters or painters. Formal apprenticeship programs exist in which workers earn certification in specialties and become skilled journeymen.
A general worker may choose to earn the certification needed to handle hazardous materials and waste at construction sites. Alternatively, the construction worker may decide to earn a bachelor's degree to advance to construction management and administration. Untrained general laborers sometimes get hired for construction work straight out of high school or technical school. Unions generally want physically fit applicants who can work well with others, such as individuals with military backgrounds.
