Silicosis is a lethal workplace illness that killed thousands each year up through the 1960s. In recent decades, thanks to union workplace safety fights, it became much rarer. Annual deaths dropped to the hundreds. The disease affected mostly older workers with longer exposures. So it was hard for stonecutter Gustavo Reyes Gonzalez, 35, to get a clear diagnosis in 2019 when he first developed a cough and shortness of breath. It wasn’t until two years later that he was told he had silicosis—and only had a year to live.
