Equal pay starts with data but ends impacting organisational culture

Every year, International Women’s Day brings renewed attention to the progress made in gender equality, but also to the gaps that continue to persist. Among the many themes discussed on March 8, equal pay remains one of the most tangible and measurable indicators of fairness in the workplace. While the conversation has evolved from awareness campaigns to regulatory frameworks and corporate reporting, the reality is that pay inequality still shapes women’s professional lives across industries, seniority levels and geographies.

Equal pay has become a strategic business issue, a reputational factor and, increasingly, a legal obligation. In the context of International Women’s Day, examining equal pay also means looking beyond salary numbers to the structural realities that influence compensation, including representation in leadership, access to decision-making roles, transparency in pay systems and the data infrastructure that enables accountability.

The gender pay gap and its long-term impact

The gender pay gap is, at its core, the average difference in earnings between men and women across the workforce. It shows in obvious ways how two people in similar roles earn different salaries, but in fact runs deeper than that. It reflects how certain professions become gender-segregated, how promotions sometimes follow uneven paths, how part-time work affects long-term income and how roles traditionally associated with women have historically been valued less.

Across Europe and globally, the conversation has moved forward step by step, yet the gap still remains visible. The real work goes beyond adjusting a number in a spreadsheet, it means reshaping the systems and habits that quietly recreate inequality year after year. International Women’s Day often brings this into sharper focus, reminding us that equal pay is closely tied to financial independence, career stability and even the quality of retirement years.

Leadership representation and the upper management barrier

One of the most visible contributors to pay inequality is how few women reach the top. Gender balance often looks better at entry and mid-management levels, but it thins out sharply in executive teams and boardrooms, especially in sectors like tech or finance. This matters because senior roles come with bigger salaries, bonuses and influence. When women are missing from those seats, the pay gap naturally widens, and the decisions shaping promotions, culture and compensation stay less diverse. More women in leadership doesn’t fix everything overnight, but it creates the space for fairer and more balanced choices.

Equal pay moves from HR topic to boardroom priority

In recent years, equal pay has shifted from a line in CSR reports to a real business priority. New regulations, employee expectations, investor attention and the race to attract talent have all pushed companies to treat pay fairness as strategy, not symbolism. 

Insights from the European payroll and HR research conducted by Forvis Mazars - Compliance, accurancy and visibily: the 3 non-negotiables in modern European payroll, show that compensation transparency and fairness are increasingly perceived as central organisational challenges. The study highlights that 45% of HR leaders cite compensation and benefits as a major challenge, confirming that pay equity is no longer treated as a secondary topic but as a strategic concern with direct implications for trust, retention and compliance.

The research also shows that 51% of organisations select payroll providers based on stronger compliance support, underlining how pay equity is now closely linked to credibility and risk management.

Data visibility as the foundation of fairness

“As we reflect on progress around equality this March, it is no longer enough for companies to simply declare that they do not discriminate in pay for work of equal value or that they pay fairly across the organisation. Today’s employees expect evidence - data that demonstrates equity, transparency in how reward systems are designed and clear pathways showing how performance and career progression influence pay.”, mentioned Florina Ilie, Senior Manager, HR & ESG Advisory, Forvis Mazars in Romania.

One of the most overlooked pieces in the equal pay puzzle is data quality. Without accurate payroll and HR data, companies simply cannot see where gaps exist or track real progress. Payroll systems hold a huge share of a company’s sensitive and strategic information, from salaries and bonuses to working hours and long-term employment trends.

According to the Forvis Mazars European payroll study, around 70% of business-critical data flows through payroll systems, yet many organisations still use only a fraction of this information when making strategic decisions. At the same time, there is a clear paradox: although payroll contains most of the workforce data needed for pay equity analysis, only 17% of companies use automated systems for compliance monitoring. In practice, this means many equal pay checks still rely on manual spreadsheets and occasional audits, which increases the chances of blind spots and slower corrective action.

From “nice to have” into standard practice

Equal pay audits are quickly becoming the norm.  The European payroll research shows that 47% of organisations already run regular internal or external payroll audits, while 53% work with external payroll, legal or tax advisors to keep accuracy and compliance in check.

This signals a clear shift, while pay equity now sits at the intersection of finance, legal and executive decision-making. The same study also highlights that 32% of HR leaders see labour agreements and legal compliance as major challenges, showing that equal pay lives as much in contracts and regulations as it does in salary grids.

Across Europe and beyond, pay transparency is moving from optional to mandatory. New regulations increasingly ask companies to report gender pay gaps, share salary ranges in job ads and take action when differences pass certain thresholds.

The Forvis Mazars research shows that equal pay audits are rising as a strategic priority, pushed both by regulation and by employee expectations. Transparency changes the rules of the game, while companies are expected to show real, data-backed progress, while employees gain clearer ground for open and informed conversations about compensation.

Organisational culture beyond numbers

Policies, audits and data matter, but culture is what makes equal pay last. Real progress happens when fairness is part of everyday decisions: how people are promoted, evaluated and supported, not just an annual report. Training managers need to talk openly about compensation, offering flexible work options and creating mentorship paths all help reduce hidden biases and keep talented women in the pipeline. Data can show the gaps, but culture decides whether a company actually closes them. Equal pay is both a numbers issue and a people issue.

Beyond ethics and compliance, equal pay also makes clear economic sense. Companies with fair pay structures often see higher engagement, lower turnover and stronger employer brands. Diverse leadership brings broader perspectives and more innovation, while at a larger scale, narrowing the gender pay gap boosts purchasing power and economic stability. Equal pay becomes both a business advantage and a societal investment.

International Women’s Day plays an important role because it shines a spotlight on these conversations and creates momentum. But real change happens after the campaigns end. The most meaningful actions are the ones tied to accountability, publishing pay audits, setting measurable diversity goals or investing in leadership programs for women. March 8 can start the conversation, yet progress depends on what companies choose to do the rest of the year.
