The causes of the pay gap are well-rehearsed, and include a range of societal and economic factors which inter-relate in complex ways. Gender norms and stereotypes based on assumptions about girls’ and boys’, and women’s and men’s capabilities, skills and interests results in gender segregation in subject choice and then patterns of occupational segregation. Women are concentrated in female-dominated, low-paid, undervalued jobs such as admin, care and retail, while men are more likely to work in higher paid, technical roles. Women remain disproportionately responsible for care for children, sick people, older people and disabled people, and a lack quality part-time and other types of flexible working to enable them to balance work with family life means that many women are working below their skill level.
