Entre el sindicalismo y el progreso (Between Unionism and Progress) is a series of poems published in the form of telegrams, based on the writings of Mexican telegraphists in 1947, the same year that marked the end of World War II and the establishment of the first international organization, the International Telegraph Union (now the International Telecommunication Union, ITU).

Due to their ability to sense the pulsations of words, telegraphists developed a heightened sensitivity to the rhythm of language. They wrote poetry about everyday situations, prompting me to reissue their poems in various languages that speak of the decline of national progress, directing them to the International Telecommunication Union.
