Evolution of labor comprehension The 1st table shows the milestones of views evolution on labor and its categories. In the period of agrarian way of life of society the category of labor was not studied specially. It was realized likely on the initial level. And the scientific research of labor is connected with the names of A. Smith and K. Marx in 18-19 centuries. Thus, K. Marxintroduced the concept of workforce (ability for work). The further understanding of labor as a category has a humanistic vector and is based on the concepts of human capital. Such labor categories as content, character and its role in economy had changed towards humanism and intellectual labor. Its vividly seen in the dramatic changes of labor content at the beginning of the 21st century from agrarian and craft work to mostly intellectual and creative work. So the satisfaction from labor grew up rapidly. As a result it reflected on the methods of human resources management. If in Taylor times there was a complete regulation and full control, to the times of Swaybie and L.Edwinsson the workforce is presented as an intangible asset and the intellectual type of corporate culture is emphasized. The modern researchers such as A.I. Rofe, J.P.Kokina and P.E.Shlender, J.M.Ostapenko consider labor as a conscious focused activity directed to the production of some socially useful products- immaterial or material.
