Laborers and movers of freight, stock and material
Material-moving workers generally fall into two categories (1) Operators who use machinery to move construction and other heavy materials, usually over short distances — around construction sites, factories or warehouses. (2) Laborers who move freight, stock or other materials by hand. They may also clean vehicles, machinery and other equipment, and package products and materials.
Some states and cities require crane and derrick operators to be licensed.
