More information about Stefan Sagel

Stefan Felix Sagel (1973) studied Dutch law at Leiden University. After graduating there cum laude in 1997 in the specialisation Civil Law, the following year he was granted the title Magister Juris in European and Comparative Law at the University of Oxford. Since January 1999, Stefan Sagel has been working as a lawyer at De Brauw Blackstone Westbroek, where his specialism is labour law and civil  cassation, the latter particularly in the field of labour law. In the past years he has worked on a number of high-profile cases at the court of cassation, such as the proceedings concerning compensation for damages resulting from apparent unfair dismissal (Van der Grijp/Stam, NJ 2010, 493), the question whether ZZP’ers (self-employed workers without employees) can fall under the employer’s liability scheme (Davelaar/Allspan, JAR 2012/110) and on the scope of an employer’s insurance obligation for traffic accidents involving their employees (TNT/Wijenberg, NJ 2011, 597).

In the past, Stefan Sagel has published material on various subareas of labour law, including dismissal law, the right to strike and collective agreements law, but also on new developments, such as the consequences of obesitas under labour law. In 2013, he obtained his doctorate at Leiden University on a thesis on dismissal with immediate effect.  

In addition to his work as professor and lawyer, he is also editor-in-chief of the magazine Rechtspraak Arbeidsrecht, a member of the editorial staff of the magazine Tijdschrift Recht en Arbeid, a contributor at the Nederlands Juristenblad, a lecturer at the Studiecentrum Rechtspleging and Deputy Justice at the Court of Appeal in The Hague.
