Changes in the content of work in particular working professions
(RESUME)

Analysis of changes in the content of three working professions (turner's, fitter's and assembler's, and tractor driver's) from 20-ies till present days allows the author not only to represent some trends in the scientific-technical progress, but also to show how this progress requires development of a new professional structure in qualified labour.
