1. Why Telephone Reference Calls Are So Decisive in Switzerland
Under Swiss employment law (Article 330a of the Swiss Code of Obligations), employers are legally obligated to formulate written work certificates (Arbeitszeugnisse) in a benevolent manner that does not unfairly compromise the employee's economic future. In practice, this statutory benevolence often results in coded, highly polished, and diplomatic documents where true differences in work performance can be difficult to discern.
To evaluate genuine problem-solving capabilities, cultural fit, work discipline, and stress resilience, Swiss hiring managers and SME owners prefer to pick up the phone. A focused 10-minute conversation with a former line manager provides far more reliable and nuanced data than ten pages of certificates.
In the Swiss hiring workflow, reference checks are rarely conducted during initial screening; they are the final hurdle when only the top two or three candidates remain. A glowing reference call triggers the formal contract offer, whereas hesitations or lukewarm praise can derail an otherwise strong application.
