Education and career

Thomas successfully completed his Bachelor’s degree in Law at Leiden University, graduating with a major in Law, Entrepreneurship & Management.

While at university, Thomas was an active member of the Leiden employment law student association Sine Labore Nihil, performing committee work such as organising the annual employment law conference.

Thomas’s daily practice

‘My daily practice is a combination of employment law and employment participation law. This includes matters concerning dismissal, reorganisation and restructuring, competition clauses, collective labour agreements and leave. I also regularly draft and modify model employment contracts and complaints procedures. In addition to the above, I guide works councils and directors on employment participation processes with respect to the right of consultation and consent, and I provide advice and guidance on the establishment of works councils. The breadth of my practice means that every day is different, and highly enjoyable.’

4 March 2025

Approximately one-third of working Dutch people experience cross-border behavior in the workplace.
