Kernrechtsfrage
Whether the employer had a valid important reason for immediate termination under Art. 337 OR based on alleged indiscretion, refusal to communicate, and discourtesy.
Extrahierter Entscheid
The alleged grounds were not sufficient. The employer forfeited reliance on the claimed refusal to telephone or attend a meeting, and the remaining conduct after warning did not justify summary dismissal.
Extrahierte Begründung
A summary dismissal requires a particularly serious breach, or repeated lesser breaches after a clear warning. The employer did not immediately dismiss or reserve dismissal based on the alleged telephone-refusal ground, and the conversation-refusal ground did not exist because the employee attended the later meeting. The warning of 12 February 2001 covered only specific conduct and could not extend to all later tone-related disagreements, especially after freistellung.
