As the functional role of science in the development of the economy expands, specialists of scientific organizations are becoming an increasingly significant subject of the social division of labor. On the basis of open data of official statistics and the results of a nationwide representative study, the authors of the article show that the expansion of the economic role of science workers is accompanied by the transformation of a large part of their intellectual activity into creative engineering for innovative production. At the same time, the labor of the majority of scientists is transforming from exclusive to mass-production, bringing the nature of their living conditions closer to the way of life of workers of mass professions, partly transforming into precarious labor. At the same time, it is shown that the formation of precariat is not a deviation in the classical form of wage labor, but the transformation of the proletariat as a class into precariat, which is also characteristic of scientific workers.
