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.’
