Question juridique clé
Whether the contractual clause requiring reimbursement of training-related salary paid during course absences was arbitrarily applied and valid.
Solution extraite
The cantonal court did not apply federal employment law arbitrarily in requiring reimbursement of salary paid for training time that was not necessary for the work performed.
Motifs extraits
The training improved the employee's professional capacity rather than being indispensable to the job; the parties could validly agree to treat course hours as working time and to require repayment if the employee left early.
