Trabalho, Educação e Saúde - TES (Work, Education and Health) is an open access scientific journal, edited by the Joaquim Venâncio Polytechnic School of Health, from Oswaldo Cruz Foundation.
In advanced capitalism, in all industries the labour process has become essentially semiotic, that is, in all steps of the productive chain, from engineering to machine adjustment and control, workers are employed to process information to which they can attribute meanings related to concrete labour situations. Understanding this process helps to understand the Marxian concept of concrete labour and can contribute to a better understanding of the nature of the informational capitalism that has been emerging in the beginning of this century.
