In 1940, following the Armistice with France, Goldberg was expelled from the army under Hitler's order of April 8, 1940, which stated that all first-degree were to be discharged from the military. He returned to his former workplace, which had now changed its name to "Feodor Schmeider", having been obliged to remove the Jewish name "Schneller". Goldberg played an increasingly responsible role within the company, obtaining contracts for uniforms from the army and the navy. He also attended the Reich Committee for Labour Studies school (, RAFA), where he was one of the four out of 80 students who passed the test to become a REFA teacher. He then became a Labour Studies Board lecturer on the clothing industry, and delivered lectures to organizations and company directors, even publishing an article in the weekly trade publication "Textilwoche".
