Key legal question
Whether the cantonal court arbitrarily established six weekly hours of overtime for housekeeping and babysitting work.
Extracted holding
No. The Federal Court held that the challenge was merely appellatory and that the factual finding was not insupportable.
Extracted reasoning
The cantonal court was entitled to estimate overtime by analogy with Art. 42(2) CO after taking evidence. Estimation necessarily involves uncertainty, and the appellants did not show manifest inaccuracy or arbitrariness.
