Female Wage Labour', which argued that women should be understood as an unrecognised 'reserve arm of labour'. In response, Floya Anthias published 'Woman and the Reserve Army of Labour: A Critique of Veronica Beechy', to query Beechey's arguments, while also recognising that it Beechey's was "the most sophisticated and influential attempt to analyse women's wage labour by using or reconstituting the categories of Marx's Capital". In 1987 Verso published Beechey's collected essays on women's participation in labour as the book Unequal Work.

They did not see a true possibility to unite across economic inequality because they argue that it would be extremely difficult for an upper-class woman to truly understand the struggles of the working class. For instance, Kollontai wrote in 1909: For what reason, then, should the woman worker seek a union with the bourgeois feminists? Who, in
