The motherhood penalty - the loss in lifetime earnings experienced by women raising children - has become the most significant driver of the gender pay gap. Prompted by the underemployment and slower career progression women experience on returning to work after childbirth, it is perpetuated by the unfair share of childcare women take on in almost every country around the world.
In the UK, the childcare affordability crisis and low take up by fathers of shared parental leave threatens to exacerbate gender inequality, and is pricing a growing number of women out of work. The shared parental leave system was introduced to encourage fathers to take more parental leave. However, it has had very low uptake from families, estimated at just 2-8% in 2019.[1]
Affordable childcare is critical in helping to ease the pressure on mothers and families, and reduce women’s unpaid care load. This needs to be complemented with policy solutions that aim to redistribute unpaid childcare more equally between women and men.Redesigning parental leave policies to support a ‘dual earner-dual carer model’ would help to shift underlying societal attitudes around gender roles and care over time.
Our economic analysis suggests an effective Equal Paid Parental Leave system in the UK would benefit women, as well as men, families, wider society, and employers. We have quantified some of the expected benefits to women and across society of fathers taking more parental leave. Our analysis begins to explore the potential economic and societal return on investment of moving towards a ‘dual-earner dual-carer’ model and a system of Equal Paid Parental Leave in the UK.
Our analysis shows that if fathers took more parental leave, there would be sizable and long-term benefits for women, families and society in the UK.

“An 18 year old woman entering the workforce today will not see pay equality in her working lifetime. At the rate the gender pay gap is closing, it will take more than 50 years to reach gender pay parity.
If the rebound from COVID-19 has taught us anything, it is that we can’t rely on economic growth alone to produce gender equality - unless we want to wait another 50 years or more. We must design and develop policy solutions that actively address the underlying causes of the inequality that exist today.”
