(1) Even though the documents required to get the retirement benefit varies, we will highlight essential records to prove building workers years of service and contribution:

Attestation of Services and Payments granted and certified by the employer and the Contribution Book by the Institute of Statistics and Register of the Construction Industry (IERIC), of all the companies you have worked for. For those beneficiaries of the Unemployment Insurance, it is important to keep all the payslips.

If you couldn´t get the required documents, you can show other documents to prove the servicies. Such as: payslips, job certificates, social service card, which can be essential instruments of evidence in those cases that workers can´t  get the attestation of services or the contribution book has been lost.
