A more thorough explanation:

Definition: A laborer is a person who earns a living by doing physical work.

For example, a construction worker who carries heavy materials and uses tools to build structures is a laborer. Another example is a farm worker who plants and harvests crops by hand.

These examples illustrate the definition of a laborer because they both involve physical labor as the primary means of earning a living. A laborer may work in a variety of industries, including construction, agriculture, manufacturing, and transportation.
