Supreme Court allows award based on equal treatment principle overriding collective agreement rules.

The Supreme Court of Poland overturned the lower court's dismissal of a claim for a jubilee bonus, ruling that the collective agreement must be interpreted to ensure equal treatment of employees. The plaintiff, a long-term employee, argued that the new collective agreement unfairly denied him a bonus he was entitled to under previous rules, while the employer contended the new terms applied strictly. The court held that applying the new rules would create unequal treatment compared to hypothetical employees starting work at the same time, thus allowing the claim based on the principle of equal treatment.
