The Certificate of Employment Letter (Arbeitszeugnis) is a fundamental document in Swiss employment law and business culture. It is issued either upon an employee's request during employment (interim certificate) or at the termination of the employment relationship (final certificate). Required under Article 330a of the Swiss Code of Obligations, this document serves multiple purposes: it provides official proof of employment, details the nature and duration of work performed, and includes an evaluation of the employee's performance and conduct. The certificate must adhere to specific principles including truthfulness, completeness, clarity, and benevolence. It plays a crucial role in Swiss employment practices, as future employers typically require these certificates as part of their hiring process. The document must be carefully worded using standard Swiss phrases that have developed specific meanings in employment context.
