Employment & Employee Participation

Thomas mainly advises employers and works councils of varying sizes in diverse sectors, such as healthcare institutions, IT companies, and public sector organisations. He also regularly advises individual employees and directors. Thomas provides advice in a wide range of areas, ranging from reorganisations and dismissal to consultation and consent processes.

‘I am an approachable, keen and dedicated lawyer with a positive attitude. I am energised by finding the best solution in every situation, based on the client’s best interests.’

Education and career

Thomas successfully completed his Bachelor’s degree in Law at Leiden University, graduating with a major in Law, Entrepreneurship & Management. During his university studies, he took employment law electives that piqued his interest in this area. In 2023 he graduated with his Master’s in Employment Law from Leiden University. 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. His successful internship with the Employment, Employment Participation & Mediation team led to Thomas joining De Clercq after obtaining his Master’s degree. In 2024, he will commence studies at the Professional Law School (Beroepsopleiding Advocaten).

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.’
