Working another job during sick leave automatically forfeits the entire sick pay entitlement.

The Supreme Court dismissed the cassation appeal, upholding the Social Insurance Institution's decision to deny sick pay for the entire period. The applicant argued that performing additional work did not worsen his health or extend his disability, citing a lower court's finding of medical necessity. The court ruled that merely engaging in another paid job contradicts the fundamental purpose of sick leave, which is to provide maintenance without work or income.
