Kernrechtsfrage
Whether the cantonal court arbitrarily found that the employee did not know the amount of vacation pay included in the piecework wage from the outset.
Extrahierter Entscheid
The challenged finding was not decisive for the outcome, because valid vacation pay offsetting requires itemized disclosure on wage statements and, in a written contract, a written agreement specifying the vacation portion.
Extrahierte Begründung
Even if the finding were incorrect, the legal requirements for valid vacation pay inclusion were not met; therefore the complaint could not succeed on that point.
