SINTEC-RS is the result of the enthusiasm and dedication, often anonymous, of fellow Industrial Technicians who, over time, worked to build a professional entity and consequent union entity.

September 23 is Industrial Technician's Day and it was on that day, in 1987, with the signing of the Union Charter, that the existence of the Union was ratified.

SINTEC-RS is the entity that legally represents, throughout the State of Rio Grande do Sul, Industrial Technicians and aims to promote professional practice. To this end, it works with the Professional Councils, forwards agreements, agreements and conventions, always seeking to defend the interests of the category.
