Combining ‘strong legal expertise and a sharp understanding of clients’ operational challenges’, Arendt & Medernach remains a popular choice among large domestic and international employers to advise across a broad swathe of their most pressing labour law issues. Many of these originate from the financial services sector, where ’exceptional’ team head Philippe Schmit has a particularly profound knowledge, including on issues related to compensation and benefits schemes. Schmit is also abreast of hot-button employment issues, including as it relates to the relatively new whistle-blowing law which took effect in Luxembourg in 2023. Jean-Luc Putz is also a key contact and has a particular expertise at the intersection of employment and criminal law.
