We study how changes in the distribution of occupations have affected the aggregate non-pecuniary costs and benets of working. The physical toll of work is smaller now than in 1950, with workers shifting away from occupations in which people report experiencing tiredness and pain. The emotional consequences of the changing occupation distribution vary substantially across demographic groups. Work has become happier and more meaningful for women, but more stressful and less meaningful for men. These changes appear to be concentrated at lower education levels.
