“The employment patterns of women in the UK have changed significantly. For instance, according to the 1911 Census, about 28% of all women in England and Wales worked in domestic service.
Women’s employment changed significantly during the two world wars, and they played vital roles in war-related industries like the production of ammunition. While 23.6% of women were employed in 1914 (Anitha and Pearson, 2013), this increased to 36% in 1918. At the peak of World War 2, up to 90% of single women aged 18 to 40 years were engaged in national service activities. Therefore, the world wars transformed the structure of the labour market, creating opportunities for women in sectors that were formerly dominated by male employment.
Outside periods of war, women’s position in the labour market was more marginal. A combination of explicit rules and social norms meant that women faced limited opportunities to work, and where work was available it was often less well paid.
Since World War 2, the position of women in the labour market has changed radically. Industrial changes, incremental improvements in legislation and shifting social attitudes have all contributed to a significant increase in female participation in the labour market. Table 1 shows the number of women aged 16 years and over who were engaged in economic activity between 1951 and 2018 (in 10-year averages). It shows that female economic activity increased by nearly 2.5 times over the period 1951 to 2018.”
“We can learn more about women’s labour market participation by comparing female and male participation rates over time. Figure 3 shows a comparison of the participation rates between 1971 and 2018. The participation of women increased steadily over time, from 55.5% in 1972 to 74.2% in 2018. Although male participation remained higher, it fell from a high of 94.9% in 1971 to 83.7% in 2018.”
The above is all work, both FT and PT,
“The share of full-time employment taken by women has increased over time from 29.0% in 1984 to 37.6% in 2018. Legislative and cultural change are likely to be factors here, just as they contributed to overall rises in employment.
Historically, women have dominated part-time employment. In 1984, they accounted for 87.3% of part-time workers. While still in the majority, that proportion fell to 73.3% in 2018. Several factors explain the fall, including:
a rise in the age of women having their first child
an increase in the population (and especially that of younger women in the workforce)
the introduction of childcare vouchers and other legislative changes that facilitate mothers’ working on a full-time basis”
