While an hourly rate makes it easier to compare wages with those in the United States, the daily rate is crucial for certain benefits and legal requirements. For instance, Christmas bonuses (the Aguinaldo) are mandated by law. At least 15 days of pay at the employee's usual daily rate is required as a Christmas bonus by law. Unions and senior employees may negotiate for larger bonuses, but they are still typically expressed as a number of days at the employee's daily rate.
