In which year did the ILO first discuss technological unemployment?

The available evidence does not establish a definitive first year. It identifies 1933 as the earliest year found in the sources, when the International Labour Review published E. Lederer’s article “Technical progress and unemployment,” but it does not prove that this was the ILO’s first-ever discussion of the subject.^[1] The issue became especially prominent in ILO policy debates during the 1960s, though the cited evidence does not specify a single calendar year for the beginning of those debates.^[2]
