what were the changes in kind of work available to women in london between 19th and 20th century?explain the factor which led to these changes

Factories employed large numbers of women in the late eighteenth and early nineteenth centuries..With technological developments, women gradually lost their industrial jobs, and were forced to work within households. The social workers believed that family as an institution was breaking down in London because the women were getting economic independence. The suggestion they made was to push the women back into domestic arena. A large number of women used their homes to increase family income by taking in lodgers or through such activities as tailoring, washing or matchbox making. However, there was a change once again in the twentieth century. As women got employment in wartime industries and offices, they withdrew from domestic service.
