It pertains to:
- The exertion by human beings of physical or mental efforts, or both, towards the productions of goods and services.

Labor, in ordinary signification, is understood as physical toil although it does not necessarily exclude the application of skill, thus there is skilled and unskilled labor.
Skill, by dictionary definition, is the familiar knowledge of any art or science, united with readiness and dexterity in execution or performance or in the application of the art or science to practical purposes.
