Questione giuridica chiave
Whether the cantonal court arbitrarily assessed the evidentiary value of the handwritten commission plan when fixing salary and rejecting vacation/fee claims.
Decisione estratta
No arbitrariness: the document could be treated as an unfinished draft with unclear content and no decisive probative force.
Motivazione estratta
Its handwritten, provisional character, later pencil annotations, lack of signatures or party names, and the parties' subsequent conduct supported the finding that it was only a draft.
