For that purpose, all our workers are company employees, we don’t believe in outsourcing because we think quality and work control are lost if we follow this way. Due to that, all our staff has the necessary and mandatory formation, and also counts with all the homologated training from the main market manufacturers QROMIA is working with in its different business areas.
