Key legal question
Was the employee's fixed monthly salary 8,000 CHF or reduced to 5,500 CHF from March 1995?
Extracted holding
The fixed salary remained 8,000 CHF per month; no valid agreement on a mandatory reduction was proven.
Extracted reasoning
The lower court's trust-based interpretation was upheld: the employee never accepted the reduction, the later signed contract again provided for 8,000 CHF, and the minutes only showed discussion of a lower salary, not agreement.
