[1] Otte moved to Bocholt in 1911, where he was again elected to the city council, and was chair of the local branch of his union.
[1] The Central Association was affiliated to the United Federation of Christian Trade Unions in Germany (GCGD), and Otte was appointed as its general secretary in 1921.
The following year, after the Nazi takeover of the country, the GCGD was subsumed into the German Labour Front, with Otte's acquiescence.
He represented that body at an international labour conference in June 1933, but he and fellow trade unionist Wilhelm Leuschner refused to speak in support of the Nazis.
He left the trade union movement, and died in October in a traffic accident, one which may have been a cover for an assassination by Nazis.
