Questione giuridica chiave
Whether the employee's conduct constituted just cause for immediate dismissal under Art. 337 CO
Decisione estratta
The conduct, including the altercation and earlier workplace incidents, was not sufficiently serious to break the trust relationship or justify summary dismissal.
Motivazione estratta
The court upheld the cantonal finding that the incident was limited, occurred in a construction-site context, caused no lasting work stoppage, and did not amount to a grave breach; earlier misconduct was not shown to have been validly warned and could not alter the result.
