After industrialization, more men than women went into the factory, but many low income and working class women went to work as well. In 1900, about 30% of urban women were working outside of the home in textile mills, as seamstresses, rolling cigars, folding books, etc. White women held these industrial jobs while women of color worked agricultural, domestic, and laundry work. The work for men and women was often dirty and dangerous. The upper-middle class model of white womanhood said that she did NOT work. However, nursing, teaching, and social work weren't seen as a threat to womanhood since they made use of women's "natural" talents. As more service workers were needed, secretarial work was added to the list of "acceptable" professions because women were thought to be more compliant and dexterous. Still, it was expected that these jobs were temporary until marriage or secondary to their husbands.
