This work analyzes the female participation (partnership) in the different levels (steps) of the labour organization in computer field (artesanal, systemic, flexible). An analysis of the literature shows that the grade crossing is not neutral with respect to gender relationship. Different tools are used in this analysis. Firstly, concerning Brazil, information extracted from the labour Ministry data bases RAIS and CAGED between 1986 and 1996, allow us to draw an image of the formal market for the computer field professional groups. Next, in view of the tendency of the labour relationships which becomes more and more casual in the field, this analysis is extended through the self observation of the cascade of subcontracts for the jobs in computer sciences field in a bank of Rio de Janeiro. Both tools confirm that there exists a kind of "excluding insertion" of the women which appears in several ways in each of the different levels of the labour organization of the field.
The analysis of the speeches of men and women, engaged in an affirmative action for the insertion of female manual work in the computer field within the NOW project (New Opportunities for Women) of the European Community completes the study.
