Salary Compression: Identifying and Addressing Pay Gaps

Salary compression occurs when pay differences between employees narrow enough to create a concern—for example, experienced employees earning close to new hires or managers earning little more than their teams. It is a diagnostic signal, not proof that every small difference is unfair.

Define the relationship being tested

Specify population, comparable roles, grade, location, pay component and effective date. Distinguish compression from inversion, where a less senior or lower-level role earns more, and from general underpayment against the organisations range or market evidence.

Build reliable pay data

Reconcile fixed pay, recurring allowances, guaranteed amounts, variable opportunity and work schedule. Compare like with like and separate annualised figures from actual earnings. Account for currency, full-time equivalent, recent changes and effective dates.

Choose useful comparisons

Examine employee-to-range position, new-hire-to-incumbent gaps, manager-to-team relationships and progression across job levels. Use distributions and individual cases. An enterprise average can hide a concentrated problem in one skill or location.

Investigate causes

Possible drivers include rapid market movement, minimum-pay changes, scarce-skill premiums, inconsistent offers, delayed promotions, weak salary ranges, long periods of uniform increases or role growth without evaluation. Verify which mechanism applies before choosing a correction.

Consider legitimate differences

Experience alone does not determine pay. Role scope, capability, sustained contribution, location, shift, skill scarcity and documented market conditions may explain differences. Prior salary or negotiation strength should not become an unquestioned justification.

Assess employee and business risk

Compression can affect trust, retention, willingness to take management responsibility and internal mobility. It can also be expensive to correct broadly. Prioritise material, poorly explained relationships and critical workforce risks rather than promising immediate parity.

Model correction options

Options include targeted adjustments, range changes, promotion or job-evaluation correction, revised hiring controls, differentiated increase budgets and non-pay role redesign where appropriate. Model recurring cost, range position, downstream incentives and future increases.

Set decision criteria and governance

Reward, HR, finance and business leaders should agree evidence, affordability, priority, approval and effective date. Check related employee groups and potential new anomalies before acting. Case-specific employment, equality and tax implications need current professional review.

Communicate without exposing peer pay

Managers can explain the pay framework, role range, relevant factors, review outcome and next steps. Do not confirm another employees salary or invent a guaranteed future adjustment. Where no action is approved, address the employee concern honestly.

Prevent recurrence

Monitor offers against ranges and internal relationships, review market movement, govern exceptions and maintain job architecture. A one-time correction will erode if hiring and increase processes continue creating the same pattern.

Prioritise within an affordable plan

Rank cases using materiality, weak justification, critical role risk, duration and impact on career relationships. Consider phased correction with stated governance where full action is not feasible. Avoid allowing the first manager to escalate to consume all available budget.

Check pay equity interaction

Compression and equity analysis answer related but different questions. Review whether proposed corrections create or reduce unexplained differences across relevant groups. Use appropriate current legal and analytical expertise rather than assuming compression ratios prove discrimination.

Handle managers inside the compressed structure

A small manager differential may be reasonable when roles differ little or specialists command scarce-skill pay. Examine decision accountability, workload and career design. Do not raise manager pay automatically simply to restore hierarchy.

Example

A specialist team hired several people during a sharp talent shortage. Analysis shows new hires near the range maximum while established employees with comparable scope sit near the midpoint. The organisation validates roles and performance, models targeted changes and tightens offer exceptions rather than giving the same percentage to everyone.

Measure the response

Track relevant pay relationships, exception rates, range position, targeted adjustment completion and employee questions. Do not claim a single ratio represents pay fairness; it is one input into a broader compensation review.
