Kernrechtsfrage
Whether the employee proved entitlement to payment for alleged overtime hours under the employment contract and CCNL 98.
Extrahierter Entscheid
The employee did not sufficiently prove the overtime hours; the Federal Supreme Court upheld the rejection of this claim insofar as it was challenged.
Extrahierte Begründung
The cantonal court's factual finding that overtime was not proven was binding. The new reliance on the handwritten timesheet was inadmissible because it was raised for the first time before the Federal Supreme Court. Article 21 no. 3 CCNL 98 does not allow payment for overtime based solely on unsubstantiated assertions.
