Supreme Court distinguishes between self-employed work and employer duties to preserve sick leave benefits.

The Supreme Court quashed the appellate court's dismissal of Ewa W.'s appeal against the Social Insurance Fund's denial of her sick leave benefit. The court found the lower court erred by equating the formal legal acts of an employer with the substantive work of a sole proprietor. Consequently, the court held that performing employer duties does not constitute 'profitable work' under the relevant statute, thereby preserving the claimant's right to benefits.
