"Such were the occupations that were open to women before 1918"

The First World War had been a turning point in the employment of women as circumstances obliged them to take over many jobs which had traditionally been the sole preserve of men. However, progress made during this period was not sustained in the aftermath of the war, and did not affect the continuing paucity of women employed at higher levels in public and business life.

As the narrator dates the changes in women's employment to the end of the First World War, she may also be referring to differences brought about by their being partially granted the franchise in 1918.
