Question juridique clé
How should the clause 'advances of commissions (guarantee 6 months) CHF 6,000' be interpreted under the employment contract?
Solution extraite
The guarantee meant the employee would not have to repay the monthly commission advances during the first six months; repayment could only be required thereafter.
Motifs extraits
Applying Art. 18 CO and the reliance principle, the contract as a whole showed that the six-month guarantee attached to the commission advances themselves, not merely to the word 'commissions'. The contract envisaged a fixed monthly advance and a final settlement only upon termination, so a contrary reading would deprive the guarantee of meaning.
