Kernrechtsfrage
Whether the disputed bonus was salary under Art. 322a CO or a gratification under Art. 322d CO.
Extrahierter Entscheid
The payment was a gratification: the employer retained discretion, the amount was secondary to salary, and the employee knew the bonus practice and resignation condition.
Extrahierte Begründung
The bonus depended on the employer's assessment, was not tied to company results, had been paid for fewer than three consecutive years, and remained proportionally minor compared with annual salary.
