Kernrechtsfrage
Whether the insured earnings must be calculated on the basis of the worker's total actual income or whether pay for overtime must be excluded.
Extrahierter Entscheid
Pay for hours worked beyond the agreed 41-hour normal working week is overtime and must be disregarded when determining insured earnings.
Extrahierte Begründung
The repeated contractual and employer confirmations of a 41-hour normal week prevailed. A higher de facto workload and absence of overtime premium did not establish a tacit agreement on a higher contractual workload; the normal working time is a key element of the employment contract.
