Marble is an Amsterdam-based labour law boutique firm, founded in 2017. Our lawyers are experienced specialists who focus on all aspects of labour law. Our clients are (internationally) operating corporates in various sectors, works councils, managing directors and employees.

Marble’s lawyers are committed and do their utmost to get to know their clients inside out. This leads to good, pragmatic and compact advice. Marble offers personal attention, is service-oriented and fast. In the event of conflicts, Marble’s lawyers always strive to find constructive solutions outside the courtroom, but if there is no other option, we are happy to litigate. Marble also has a mediator in-house. Mediation techniques give us more tools to resolve conflicts, in the interest of our clients.

Conflict resolution through mediation is taking on an increasingly prominent role in society. Conflicts within the working environment can also be suitable for mediation. It can be an effective, cost-efficient and pleasant way to reach a solution. In labour mediation, parties can make agreements to improve the working relation or, on the contrary, to end it by mutual consent, with an eye for the interests of all parties involved. Where useful, we point out the possibility of mediation to our clients.

We also have mediation ‘in house’. Simon and Thijs are both experienced labour lawyers, but also mediators in labour disputes. This experience helps them to have a better understanding of what is actually going on in labour conflicts, what is important for parties to consider and which possible solutions can be found.

Other advice

Do you need advice in a field other than labour law? Then Marble can quickly arrange that for you. Marble’s lawyers have an extensive network of lawyers and other advisors with whom we work well and rapidly. Both for knowledge in other areas of law (privacy, corporate law, corporate litigation, immigration law, pensions, taxation, etc.), at home and abroad, as well as (interim) HR managers, bailiffs and other specialists.


Marble offers customization. We usually advise per hour, but it is also possible to make a price agreement for a project and a training or for temporary in-house consultancy work. The way in which the work is carried out is always in consultation with the client. We do not charge any office costs. We invoice monthly in arrears, with a detailed specification. We always try to be as transparent as possible about the time to be spent, without surprises afterwards.



We like to share our knowledge, for example by publishing blogs, sending newsletters (once a quarter) and offering (free) workshops on current topics, sometimes together with lawyers in other areas of law. Please send us an e-mail if you would like to be kept informed.
