On December 6, 1918, typesetters from the Sfetea and Minerva graphic design studios went on strike demanding better working and living conditions (a pay raise, an eight-hour day, etc.). As their demands were not met, all the typographers in Bucharest announced that they would strike a week later. On December 13, 1918 (NS December 26), a large socialist demonstration of Bucharest workers took place. Its principal organisers were Rakovsky, the typographers Iancu Luchwig and Sami Steinberg, the bootmaker Marcus Iancu, the proofreader Marcel Blumenfeld, Ilie Moscovici, Frimu, Gheorghe Cristescu, D. Pop and others.
