Marval O’Farrell Mairal specialises in complex, sensitive labour matters for international corporates and embassies, among others. The practice is well-known for its labour litigation work, representing clients before all levels of the courts, and has developed proprietary software that helps to predict the outcomes of labour lawsuits to assist clients in planning defences. The team is equally adept taking on union negotiations, immigration matters, foreign currency salary payments, the winding down of Argentine subsidiaries and advising on the labour aspects of M&A transactions. One of Argentina’s most experienced labour litigators, Javier Patrón, leads the team; he is flanked by well-connected employment specialist Enrique Stile, and Diego Kelly, whose areas of expertise include compensation and union issues. Both provide significant senior-level support. Other key names include international labour and M&A expert Rodrigo Sola Torino; labour litigation veteran José María Llano; and Guillermo Osorio, whose practice is focused on representing high net worth individuals in complex labour litigations. The practice recently strengthened its ranks with the hire of five associates, including Luciana Abadin and Mariela Raczekowski who arrived from Bruchou & Funes de Rioja in November 2022.
