Problem: John Viajero was assigned from Techno Computer's parent company in Ohio to work at the Guaynabo, Puerto Rico plant. After eight months, John Traveler realizes that he works more hours than his peers in the same position. John works sixteen hours a day, every day, while his coworkers only work twelve. Seeing this, John claims this disparity to the manager and states that he is being discriminated against. The manager sends the complaint to the sole representative of the union at the Techno Computer plant in Guaynabo, since there is no right to unionize or bargain collectively in Ohio.
According to local legislation (Law no. 4-2017, art. 2.17) and international labor law recognized by the International Labor Organization, is John Viajero correct in his claim of discrimination?
