Human resource is a way of referring to a country's working people in terms of their existing productive skills and abilities. Every activity needs factors like land, labour, physical capital and human capital for its production.
No production activity is possible without human factors. It is a human resource that makes other resources useful by their wisdom and endeavours. Human resource is not only an essential factor of production but also an important element for other factors of production. It is the human resource that operates every sector of the economy whether Primary sector like agriculture, Secondary sectors like automobile manufacturing or Tertiary sector like financial services. No resource on this Earth can become useful without human endeavour. So, human resource is an indispensable factor of production.
