The Job Certification Letter (Arbeitszeugnis) is a fundamental document in Swiss employment law, required under Article 330a of the Swiss Code of Obligations. Every employee in Switzerland has the legal right to request this document during or at the end of their employment relationship. The certificate must provide detailed information about the nature and duration of employment, the employee's performance, and their conduct. Unlike reference letters in many other jurisdictions, Swiss Job Certification Letters must balance truthfulness with benevolence, following the principle of 'wohlwollende Formulierung' (benevolent formulation). This document is crucial for career development in Switzerland, as most employers require it during the hiring process. The content and format are heavily regulated by law and established through numerous court decisions, making it a standardized yet personalized document that serves as an official employment history record.
