Questão jurídica principal
Whether the employee's alleged conduct constituted just cause for summary dismissal under Art. 337 OR.
Decisão extraída
The employer failed to show a serious breach destroying the trust basis required for immediate termination; the dismissal was not justified.
Fundamentação extraída
The unproven allegation of passing internal information could not be relied on. The disputed statement about continuing the Z. system was plausibly explained and, at most, called for clarification before dismissal. The Supreme Court found no abuse of discretion by the cantonal court.
