"A convention was drawn up on June 17, 1925, in which the principle of supervision, as opposed to that of simple propaganda, was recognized, thanks to the efforts of the labour members, of whom I was one"

This quote is describing the 1925 International Labour Conference in Geneva, Switzerland. Leon Jouhaux was a French trade union leader and among the labour members present at the conference. The convention that was drawn up on June 17, 1925 was an outcome of the efforts of the labour members, of which Jouhaux was one. The convention recognized the concept of guidance, rather than that of easy propaganda. This meant that the International Labour Organisation (ILO) was offered the power to monitor the application of global labour standards, rather than just propagating them. This was a significant advance in the security of workers' rights, and it was thanks to the efforts of the labour members, of which Jouhaux was one, that this was accomplished.
