X. Nonato had been continuously employed and deployed as a seaman who performed services that were necessary and desirable to the business of N-Train Shipping, through its local agent, Narita Maritime Services (Agency), in accordance with the 2010 Philippine Overseas Employment Administration Standard Employment Contract (2010 POEA-SEC). Nonato's last contract (for five months) expired on November 15, 2016. Nonato was then repatriated due to a "finished contract." He immediately reported to the Agency and complained that he had been experiencing dizziness, weakness, and difficulty in breathing. The Agency referred him to Dr. Neri, who examined, treated, and prescribed him with medications. After a few months of treatment and consultations, Nonato was declared fit to resume work as a seaman. Nonato went back to the Agency to ask for re-deployment but the Agency rejected his application. Nonato filed an illegal dismissal case against the Agency and its principal, with a claim for total disability benefits based on the ailments that he developed on board N-Train Shipping vessels. The claim was based on the certification of his own physician, Dr. Nunez, that he was unfit for sea duties because of his hypertension and diabetes. a) Was Nonato a regular employee of N-Train Shipping? (2.5%) b) Can Nonato successfully claim disability benefits against N-Train Shipping and its agent Narita Maritime Services? (2.5%)
