Supreme Court dismisses extraordinary review, ruling factual substance of apprenticeship creates employment relationship.

The Supreme Court dismissed the extraordinary review filed by the manufacturer against the labor court's decision. The plaintiffs argued that their period of vocational training should count toward seniority for pension and future awards, while the defendant contended it should only count as work under specific 1989 regulations. The court held that the essential substance of the relationship, including payment and working hours, established an employment contract despite the formal label of apprenticeship.
