Many employees and business owners are wondering how the new sick leave rules in Poland from April 13, 2026, will work in practice. This date marks a turning point in Polish labor law, introducing regulations that fundamentally change the approach to sick leave (L4) inspections. On one hand, the Social Insurance Institution (ZUS) is gaining more powerful verification tools; on the other, patients can count on a more "common-sense" approach to their activities during recovery.
Debunking myths: what can you do while on sick leave?
For years, there has been a lot of anxiety regarding what a patient is allowed to do while unwell under Polish regulations. Could going to the store for bread result in losing your benefits? The amendment finally settles these speculations. Polish law now clearly states that "ordinary activities of daily life" are not grounds for withdrawing benefits. While on L4, you can now safely:
• Go to a pharmacy or see a doctor.
• Do basic grocery shopping.
• Take out the trash or collect mail.
• Take your dog for a short walk.
Traveling while on sick leave – a new interpretation
One of the most significant changes in the Polish legal system is the approach to staying away from home. Previously, changing your location without notifying ZUS was a direct path to sanctions. The new rules change this perspective: the mere fact of being away is no longer an automatic ground for revoking benefits.
The key question is: does the activity harm your health? For example, if you are being treated for depression or burnout, a short recreational trip may be considered a part of recovery supported by case law. However, if you go on an intensive mountain trek with a broken leg—expect trouble.
A new definition of "gainful work" – no more traps
The regulations effective April 13, 2026, provide precise definitions of two key concepts under Polish law that could lead to the loss of benefits:
1. Gainful Work: ZUS has clarified that sporadic, situational actions (e.g., a short work email, giving a password to a colleague, or answering a phone call from the boss) will no longer be treated as gainful work.
2. Activity Inconsistent with the Purpose of Leave: This refers to any action that objectively prolongs recovery, such as renovating an apartment or running a marathon during a viral infection.
ZUS gains new inspection tools
In Poland, liberalization for patients goes hand in hand with tightening the system. Inspections may become more frequent because the right to conduct them is being granted to all employers, regardless of company size. ZUS (Social Insurance Institution) can now more easily request medical documentation and refer patients for additional examinations by medical examiners to eliminate "fake" sick leaves.

Summary of the new sick leave rules in Poland 2026
The new sick leave rules in Poland from April 13 are undoubtedly a step toward a modern state that trusts its citizens while effectively reacting to abuses.

As long as your actions do not conflict with medical advice and are not gainful in nature, your benefits are secure.
