Polish labor law amendments in 2026 will alter how past and future seniority is calculated for accrued vacation days.
The Legal Change
Amendments to Poland’s labor code will revise the method for calculating work seniority (staż pracy) for determining accrued vacation entitlements.
These changes, effective from 2026, directly impact how past periods of employment count towards accumulated leave.
Impact on Accrued Leave
The new rules will redefine how existing vacation leave, already earned but potentially not taken, is valued based on the updated seniority calculation.
Employees with accrued leave may see adjustments to how much they are entitled to under the new framework.
Future Entitlements
Going forward, the calculation of new vacation leave will be based on the redefined seniority rules.
This means the way future vacation accrues will differ significantly from the current method.
The changes aim to standardize seniority calculations across different employment periods.
