This article aims to promote the recovery of the approach applied by Marx regarding the form of existence and manifestation of the Reserve Army of Labor (RAL). The expansion of new forms of work in the 21st century as a result of the adjustment of the working class to the needs of capital appreciation is discussed for the construction of the main argument. Subsequently, the thesis that the forms of work operating in RAL are examples of surveillance of the Marxist law of value-work is sustained. Finally, the Brazilian RAL is measured based on the PNAD (National Household Sample Survey) database and the main characteristics of the occupations that compose it are presented. These theoretical considerations reveal the possibility that the form assumed by RAL in the contemporary world represents the genuine expression of an absolutely capitalized world, a product of the development of the immanent contradictions of capitalism, discussed by Marx in Capital.
