Poland Revises How Work Experience is Calculated
Starting January 1, 2026, Poland has implemented new regulations for calculating employment history. The changes formally include the following periods in an individual's total work record:
- Work performed under civil law contracts;
- Work under agency agreements;
- Periods of running one's own business;
- Time spent on childcare leave.
These adjustments are significant for workers' rights, as total work experience directly impacts the length of paid annual leave, eligibility for seniority bonuses, and career advancement opportunities. This reform aligns Poland more closely with broader EU labor standards.
Challenges in Verifying Employment History
Despite the new rules, many employees face challenges when the Social Insurance Institution (ZUS) rejects their claims for certain periods of work. These denials typically occur due to:
- Missing records of mandatory insurance contributions;
- Technical errors in documentation;
- Gaps in older, digitized databases.
Workers under 26 who were employed under specific mandate contracts are identified as a particularly vulnerable group in this process.
Legal experts emphasize that a ZUS rejection does not automatically mean the loss of that work period. It is possible to substantiate the claim with alternative documentation, even if the official system lacks the data. The recommended course of action is to gather all available evidence and submit a renewed, justified request to ZUS for inclusion of the disputed period. The institution is obligated to review the submitted materials. Acceptable forms of proof can include:
- Original paper copies of contracts;
- Bank statements showing remuneration payments;
- Tax documents related to the work;
- Any other evidence demonstrating the work was actually performed.
The overhaul of work history calculation rules represents a major step toward strengthening social protections for Polish workers, granting them expanded rights and opportunities. It is crucial, however, for employees to be aware of their right to appeal ZUS decisions, as these rulings can have long-term financial and professional consequences. Given the new framework, workers should meticulously maintain their employment records and utilize all available avenues to verify their complete work history.
