Question juridique clé
Whether the cantonal court arbitrarily interpreted the collective agreement's requirement of a prior written warning before dismissal for breach of contract.
Solution extraite
No arbitrariness was shown: earlier written warnings and reprimands could count as prior written warnings under the collective agreement, even if issued before its entry into force and without an express dismissal threat.
Motifs extraits
The court found the wording of the agreement did not require the warning to be outside disciplinary proceedings, to contain an express threat of dismissal, or to lose effect after time. In addition, several warnings made it reasonable for the employee to foresee dismissal.
