Key legal question
Whether the cantonal court acted arbitrarily by holding that overtime worked in 2000 was compensable despite lack of express order or approval.
Extracted holding
No. The employer's presence at the workplace and continuous access to schedules allowed an implicit finding of approval.
Extracted reasoning
Under Art. 321c(3) CO, overtime is payable; the court could infer approval from the employer's access to planning documents and presence on site.
