Wage Indexation

Wage indexation (also known as salary valorisation) is the practice of increasing employees' wages in response to rising prices and living costs, i.e. inflation. Its purpose is to maintain the real value of wages – ensuring that purchasing power does not decrease despite rising prices.

Wage Indexation and Inflation

Key to understanding indexation is the difference between nominal wages (the amount an employee receives) and real wages (how much they can actually buy with it). During periods of high inflation, an employee's nominal wage may remain unchanged, yet its real value decreases. Indexation aims to counteract this by adjusting salaries to the rate of price increase (most often the CPI published by GUS).

Is an employer obliged to index wages?

In Polish labour law, there is no general obligation to valorise wages in the private sector according to the inflation rate. However, there are exceptions and situations where indexation is required:

• Minimum wage – is legally valorised and increases independently of the employer's decision; this necessitates raising the lowest rates within the company.
• Collective labour agreements and remuneration policies – if they contain indexation clauses, the employer is bound by them.
• Public sector – where valorisation rules derive from separate regulations.

In other cases, the decision to index wages is part of the remuneration policy and a voluntary practice by the employer, often used to retain employees and protect their purchasing power.

How to implement wage indexation in your company?

1. Set a budget – determine the amount of funds the company can allocate to pay rises.
2. Choose a reference indicator – most often the annual CPI inflation rate (GUS).
3. Select a model – percentage (a uniform % for all), fixed amount (a constant sum, more beneficial for the lowest earners), or a hybrid approach.
4. Link to performance appraisal – many companies combine indexation with individual performance reviews, differentiating pay rises. Our Employee Performance Reviews module can help with this.
5. Communicate changes – transparently explaining the principles builds trust and reduces feelings of unfairness.

Note: It's important to distinguish indexation from performance-based pay rises. Indexation maintains the real value of salaries and is not a reward for development or increased efficiency – these should be remunerated separately.
