The Decree for the Collectivisation and Worker Control of Industry and Trade drafted by Minister Josep Tarradellas and passed by the Generalitat wrestles control of the company from Uriach.

The business becomes Uriach Empresa Colectivizada (Uriach Collectivised Company). However, Juan Uriach Tey is appointed manager by the workers who take over ownership of the company in recognition of his technical and business know-how.

The company loses 50% of its workers, limiting its activity at a time when blackouts and disruptions in the supply of raw materials are taking their toll.

However, Uriach continues to develop its business activity, as reflected in the list of pharmaceutical deliveries issued by public authorities. As a curious aside, Uriach distributed 7,500 kg of cod liver oil in 1938.
