Felipe Chirinos, Lawyer at ONTIER Peru, starts his article at Jurídica- El Peruano with a clear statement 'In Peru, the 13th month pay is rightfully granted to employees twice a year as a social benefit.' According to Chirinos, these benefits must be paid to employees twice a year in specific periods of time.
Chirinos also mentioned the reform brought by Peruvian Act 27735, by which 13th month pays are regulated and considered compulsory for companies to pay. These benefits weren't compulsory in the past.
Felipe Chirinos notes that these benefits are related to all types of open-ended contracts started at least one month prior to getting the 13th month pay. However, employees with training contracts don't have the right to be given this pay, but they could be given a compensation amounting to half their monthly retribution as specified by the contract.
