Key legal question
How to qualify the parties' training relationship: apprenticeship or instructional contract?
Extracted holding
The relationship was an apprenticeship under the Code of Obligations, in substance a free apprenticeship governed only by contract law.
Extracted reasoning
Practical work predominated, the plaintiff was integrated into the defendant's salon operations, and she worked profitably for paying clients; these elements pointed to apprenticeship rather than a mere instructional contract.
