One of the largest labour and employment teams in Argentina, Marval O’Farrell Mairal is regularly turned to by leading domestic and multinational clients seeking advice on employment agreements, international hiring and termination procedures, compensation structures, and company policy and regulations. The team is also recognised for its litigation expertise, often representing clients before the Supreme Court as well as local and regional courts, and for handling internal investigations, compliance breaches, and data privacy matters.

Paola Forchiassin, who assists corporations with day-to-day employment matters, and Jorge Rovillard, whose areas of expertise include collective labour matters and union negotiations, provide support at the associate level.
