Questione giuridica chiave
Whether vacation pay was validly included in the salary and commissions
Decisione estratta
No. Vacation pay could not be validly incorporated because the contracts and wage statements did not clearly and separately indicate the vacation component.
Motivazione estratta
Art. 329d CO is mandatory. Inclusion of vacation pay in ordinary salary is only exceptionally valid if objective reasons justify it and the vacation share is clearly stated in the contract and each payslip. Those conditions were not met.
