The court in Albertville also ordered the director of Yorkshire-based Le Ski, Nick Morgan, to pay 9,000 euros in damages to France's SNMSF ski instructors union and its training facility.
In its ruling on Monday, the court rejected the company's contention that the guides were providing only tours of ski areas and not acting as formal instructors, who can only work under French licenses.
It was ordered to pay 15,000 euros for failing to follow licensing regulations and to pay 11,250 euros for paying below the French minimum wage and failing to pay government social charges.
