Key legal question
Whether the employee proved overtime entitlement and its amount under Art. 321c OR.
Extracted holding
The complaint failed: the Federal Court upheld reliance on the employer's accounting entries as proof of overtime and found no legally relevant error in the amount awarded.
Extracted reasoning
The Court held that strict proof of overtime extent is often impossible; a reduced standard may apply without reversing the burden of proof. The appellate court could rely on the employer's own bookkeeping entries for transitory liabilities showing overtime/holiday credits.
