We Have the Corrected Pay Gap, Now What?

Outlier Analysis: Who’s Over- or Underpaid?

A powerful next step is identifying outliers: individuals whose salaries deviate significantly from those of their peers; colleagues with work of equal value. Not every deviation is necessarily unfair, but these outliers provide a valuable starting point for case-by-case review. Are they overpaid, underpaid, or are there justifiable reasons behind the discrepancy?

Under the EU Pay Transparency Directive, an absolute pay difference of more than 5% within a peer group must either be objectively justified or corrected through salary adjustments. Doing an outlier analysis helps with either finding objective criteria for pay differences or to spot the employees for which salary adjustments are needed. Therefore, this analysis is essential to help comply with this requirement, and more importantly, to ensure fairness within your organization.

Deeper Insights Through Pay Component Breakdown

The scope of pay components (e.g., base salary, bonuses, allowances, etc.) can significantly impact your observed pay gaps. To better understand what is driving the gap, it is useful to run the analysis with different scopes of pay components. You will see that the pay gap may appear smaller or larger depending on which components are included. Especially combined with insights from your outlier analysis, this helps you to identify which pay components contribute most to the gap and whether those differences are objective or potentially discriminatory. For the latter, corrective actions may be needed.

Simulating the Effect of Salary Adjustments

What if you increased salaries for certain underpaid employees, how would it affect the gender and/or the equal pay gap? By simulating the effect of hypothetical salary changes, you can:

  • Test different scenarios before implementing them,
  • Prioritize the most effective interventions,
  • Estimate the cost of narrowing the gap.

This kind of what-if analysis empowers you to make data-driven decisions with confidence and clarity.

Informed Pay Decisions for New Hires

Your insights derived from an equal pay analysis do not just reflect the past; they can guide the future. When hiring new employees, you can use the salaries of peers and insights from the equal pay analysis to help set equitable starting salaries, based on relevant characteristics like years of experience and job level. This helps avoid introducing unfairness when hiring new employees and ensures your pay practices stay aligned with internal standards and external demands.

Final Thoughts: From Measurement to Movement

Having an equal pay gap figure is an achievement in itself, but the real impact comes when you act on what the data tells you. Whether it is exploring outliers, refining your pay structure, or guiding new offers; a lot is possible. And we, as Highberg, can help you!

Equal Pay and Gender Pay Gap Analysis

Equal pay for equal work, pay equity, wage equality, pay gap, pay fairness, wage parity – these terms all refer to the same fundamental issue. At its core, the goal is to ensure that people performing the same work are paid equally, regardless of their background or other characteristics, and that companies can demonstrate this equality. In the Netherlands, the term "characteristic" typically refers to gender (male/female). However, in other countries, this type of analysis is also applied to other diversity factors, such as ethnicity or nationality. As the Netherlands follows pioneers like the US and the UK in this field, it is expected that the focus on pay equality will expand over time to include other diversity dimensions.

Calculate employee turnover (Employee turnover analysis)

Structurally high employee turnover is problematic for organizations. Excessive employee turnover incurs significant costs and can even impact issues such as business continuity and customer satisfaction. An employee turnover analysis, through advanced statistical analysis, identifies risk groups, helps to understand the causes of turnover, predicts how employee turnover will develop and predicts where turnover will occur. In short, deploying HR analytics on the topic of employee turnover gives organizations the tools to prevent employee turnover.
