Work on Saturday as a rest day under five-day week entitles to 50% overtime premium.

The Supreme Court dismissed the cassation appeal against a lower court ruling awarding overtime premiums for work performed on a Saturday rest day. The plaintiffs argued they were paid insufficiently for working on days designated as rest days under a five-day work week, while the employer contested the evidence regarding their actual working hours. The court held that the lower courts correctly evaluated the evidence and that cassation complaints challenging factual findings or evidence assessment are inadmissible under Polish procedural law.
