A Polish employee on full-time employment questions whether blood donation leave pay should be included in the basis for the 13th payment calculation.
Question
An employee is employed in a budget unit on a full-time basis. They receive a basic salary at a fixed monthly amount, a seniority benefit specified as a fixed monthly component, and a night shift allowance for actually worked hours.
In December 2025, they took time off work for blood donation. How to calculate the salary due for the time off work? Should it be included when determining the basis for the annual additional payment?
Answer
The salary for time off work due to blood donation is calculated like vacation pay, with full preservation of fixed components and appropriate calculation of variable components.
It is included in the basis for sick pay, but it does not increase the basis for the 13th payment.
