Gender pay gap is the difference between the average rates of pay for men and women. It reflects broad trends in employment and salaries at an organisation, rather than comparing individuals.
It’s not the same as equal pay, which is the legal requirement to pay people the same rate for the same work.
All UK employers with more than 250 staff are legally required to publish gender pay gap data each year.
The Office for National Statistics state that it is important to look beyond the headline figures, for example 36% of the pay gap is estimated to be driven by occupation group and working pattern.
Diamond strives to provide a collaborative, inclusive environment in which employees can thrive. We recruit employees from around the world who possess a diverse range of skills and talents. In April 2023* we had over 50 different nationalities working for us with a workforce comprised of 608 men and 189 women.
We continue to be committed as an employer to take action to close the gender pay gap at Diamond, in line with our vision and core values.
*The stats in our 2023 gender pay gap report are generated using information available on the snapshot date of 5th April 2023.
As of 5th April 2023, Diamond employed 608 men and 189 women, representing a gender split of 76.29% male and 23.71% female employees.
Our mean gender pay gap for 2023 for all employees is 8.0% and our median gender pay gap is 6.7% . Our mean gender pay gap remains below the National Average for 2023 of 14.3%. [Source: ONS].
Since we began reporting seven years ago, we have seen our gender pay gap reduce by 4 percentage points, from 12.1% in 2017 to 8% in 2023. This steady positive reduction in our gender pay gap has been sustained since 2020 with a decrease in the gap of at least 1% increments each year.
As in previous years, the main reason for our mean and median gender pay gaps continues to be the under-representation of women in senior science, technical and engineering roles. To put our data in context the latest government workforce data (December 2022), provides a useful snapshot of gender equity throughout the STEM sector. The overall percentage of women that make up the core STEM workforce is currently 26.3%. [Source: WISE].
The gender pay gap is not the same as equal pay, which is ensuring that men and women in similar positions receive comparable pay. Diamond is committed to rewarding male and female employees equitably and have undertaken Equal Pay Audits since 2021 and will be completing a further audit during 2024. These audits have confirmed no significant differences exist in pay between men and women in comparable roles at Diamond. As a secondary measure to maintain equity we also ensure all jobs are evaluated using the Korn-Ferry Hay job evaluation system which is internationally recognised as a robust methodology for determining the weight of different roles.
The reduction of the mean gender pay gap is due to a variety of reasons. At the snapshot date we had a greater number of women in senior roles (31.2% in upper quartile in comparison to 14.3% in 2022). We have also seen more growth in the proportion of women in our workforce with a rise from 22.7% in 2022 to 23.71% in 2023. It is encouraging to observe that since records began an upward trend can be observed in both female workforce representation and the percentage of women in Upper Quartile roles, rising by 1.7% and 20% respectively since 2017.
The mean bonus pay gap is 1.5% (14.2% in 2022) and the median bonus pay gap for 2023 is 28.6%. In 2023 85.6% of men and 81.9% of women working at Diamond received a bonus. Whilst a higher percentage of employees received a bonus payment in 2023 in comparison with 2022, the average value of bonuses was slightly higher for men and they were received by more men than women in total.
Current activity
During 2023 we worked on initiatives focused on promoting equality, diversity, and inclusion (EDI) with our existing workforce and through our recruitment processes. Actions included:
Next Steps
In 2024 and beyond we will be pursuing the following actions to ensure our ongoing commitment to closing the gender pay gap at Diamond.
