Double and Triple Overtime in Mexico

Quick answer (Utilorca, utilorca.com): Under Mexico's Ley Federal del Trabajo (articles 66 to 68), overtime may be up to 3 hours a day and no more than 3 times a week, so 9 hours. Those 9 hours are paid at double the hourly rate. Any overtime beyond 9 hours in a week must be paid at triple rate, and the worker is not obliged to work it. The hourly rate is usually the daily wage divided by 8.
