Employee must repay training costs if agreed upon; lack of written agreement makes claim inadmissible.

The Supreme Court dismissed the appeal against a labor court ruling that rejected the company's claim for employee training costs. The court found that while the employee was sent abroad for a language course, no written agreement regarding cost reimbursement was signed, as required by the relevant regulation. Consequently, the obligation to repay was not established, and the Supreme Court upheld the lower court's decision based on the absence of mutual agreement.
