Key legal question
Was the cantonal court arbitrary in relying on the employee's personal work agendas to calculate overtime and salary arrears?
Extracted holding
No. The agendas were prepared before the dispute, were corroborated by witnesses and other records, and the court could rely on them.
Extracted reasoning
Arbitrariness requires an insupportable assessment of evidence. Here the court gave plausible reasons for crediting the agendas and witness testimony, including internal consistency and corroboration by former colleagues.
