Is it necessary for the employment agreement to be bilingual with German taking precedence in Austria?

Our employment agreement in Austria is drafted in both English and German, with both versions presented side by side in a single document. In case of any discrepancies between the versions, the German text takes precedence.

Can variable compensation be included in the employment agreement in Austria, or should it be outlined in a separate Variable Compensation Plan?

In Austria, a variable compensation plan is included as an attachment to the employment agreement, referred to as a "scheme."
