Explanation:
Labor is any activity undertaken by an individual or a group of people with the aim of getting reward(monetarily or otherwise) in return for job done.
While some form of labor are skilled,others are not even though both will receive payment for work done. These laborers could be found in industries, manufacturing companies, construction companies.etc.
However, work done within the household, the family, the neigbouhood and wider community is the most prevalent form of labor around the word because it is not paid for and also carried out basically to support a common cause.
Example is when people come together within the family, neighborhood or community to construct by themselves bridge linking their community to other places, repair or fix bad roads, construct halls etc. All these are not paid for . They are service rendered for the benefit of the people within the locality.
