Gender, Age and Part Time Working

We have different age distributions of men and women within our workforce, with a peak for men in the 50 to 55 age range as shown below, whereas the peak for women is at a lower age range.

We anticipate that a large proportion of men may retire in the next ten years and hence we expect that the age and gender demographic will shift as a result. Over time, the historic legacy from when NNL was a much more male-dominated workplace, will diminish.

Number of employees in each age range split by gender. Each bar represents greater than the lower value and less than or equal to the upper value.

We know more women than men at NNL work part time (66 women, 22% of all women) compared with 46 men (6% of our men). Whilst this does not negatively impact the gender pay gap, it does have an impact on our gender bonus pay gap. The number of part-time staff, by their percentage of full-time hours (e.g. 80% is 4 days per week), is shown below.

Number of employees (frequency) working part-time, split by gender against the percentage of a full-time role that they work. Each bar represents greater than the lower value and less than or equal to the upper value so 60% FTE sits in the 50% - 60% bar.

The age distribution of the parttime workers shows that more men who are working part-time are nearer to the end of their career, whereas more women are in their mid-career. This aligns with the belief that men reduce their hours before retirement and more women choose to work part-time when they are in their mid-careers, potentially to support childcare or other caring responsibilities.

Additionally, we can see that the distribution of part-time workers by pay quartile is different by gender, with more men working part-time in the higher quartile than women. This aligns to the above where we see more men going part-time in late career, hence more likely to be more highly paid, and more women in mid-career.
