Questione giuridica chiave
Whether the employee's absences from work and training constituted just cause for summary dismissal under Art. 337 OR.
Decisione estratta
The absences, assessed as found by the cantonal court, did not amount to such a serious breach as to make immediate termination justified without prior warning.
Motivazione estratta
Unexcused absence alone is usually insufficient for summary dismissal; here the employer's additional arguments of concealment and trust breakdown did not show arbitrary or clearly unreasonable exercise of discretion by the cantonal court.
