The gender pay gap in the UK has narrowed over the last decade, but it persists and widens at certain stages of a career. 

Women remain more likely to take time out for childcare or other caring responsibilities. 

Even short career breaks can affect pay progression, bonus eligibility and pension contributions.

Part-time work is another factor. 

Flexible roles are often essential, yet they can limit access to senior positions and high-profile assignments. 

Occupational segregation also plays a role. 

Higher-paying technical and executive roles continue to be male dominated, while female-dominated sectors such as care and administration tend to offer lower salaries.

The cumulative effect is that women often earn less than men at every stage of their career. 

Fewer women in senior leadership further widens the gap, not just in salary but in bonuses and long-term incentives.

Earnings differences feed directly into long-term wealth. 

Research shows women are less likely to invest in equities and more likely to hold cash. 

They also tend to have smaller pension pots, partly due to career breaks and part-time working reducing contributions at key stages.

Confidence is also a factor. 

Women report lower financial confidence, even when their knowledge is comparable to men’s. 

Workplace financial education has not always addressed these behavioural and life-stage differences, leaving many women less confident in investing and retirement planning.

The result is that women are likely to retire with less financial security, which has knock-on effects for stress, engagement and career decisions throughout their working life.

For HR leaders, there are practical steps to reduce these gaps. Here are some ideas:

Analyse the data 

Go beyond mandatory pay gap reporting. 

Review promotion rates, bonus distribution and progression after maternity or caring leave. Identify where disparities emerge and take action.

Support return to work

Phased returns, mentoring and clear career mapping can prevent long-term earnings setbacks after career breaks.

Invest in financial wellbeing

Closing the gender pay and investment gap is not just about salaries and promotions. 

Employers can make a real difference by embedding financial wellbeing into the workplace, tailored to women’s unique experiences and life stages. 

Accessible tools and guidance, personalised pension advice, budgeting and investing support help women feel confident making long-term financial decisions. 

This practical support strengthens engagement, retention and the talent pipeline while giving women the means to build real financial resilience.

Improve pension engagement

Ensure employees understand the impact of career breaks and encourage contributions where affordable. 

Tailored sessions that explain compound growth and long-term outcomes can make a tangible difference.

Offer inclusive financial education

Cover investing basics, retirement planning and life-stage financial challenges in accessible, relevant terms. 

Building confidence is as important as building knowledge.

Review flexible working through a progression lens

Ensure part-time or flexible roles do not become career cul-de-sacs. 

Monitor promotion and visibility opportunities for employees working reduced hours.

Increase transparency and fairness

Clear salary bands, objective promotion criteria and structured performance reviews help reduce reliance on negotiation, an area where women are statistically less likely to secure pay increases.

International Women’s Day is a reminder to celebrate progress, but the real impact comes from examining structures and processes. 

HR leaders are uniquely positioned to influence pay, progression and financial wellbeing. 

Taking action now helps ensure employees are fairly rewarded, supported and able to plan for the future.

Closing the gender pay and investment gap is not a single project or campaign. 

It is a sustained commitment to creating a fairer, more equitable workplace where women can thrive at every stage of their career.
