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. Practice co-head José María Llano has over three decades of experience handling high-profile disputes across labour and social security law. Fellow co-head Enrique Stile is proficient in complex compensation structures, hiring and termination procedures, and union relations. Other key individuals include Javier Patrón, one of the firm’s managing partners and an expert in labour litigation; Diego Kelly, who frequently advises multinational and domestic corporations on M&A, employee transfers, rightsizing, and union issues; and Guillermo Osorio, another key contact for labour disputes.
