“Interior view, showing office workers in the Lever Brothers office building”

By an unknown photographer, New York City, New York, ca. 1959

By mid-century, millions of Americans worked in offices. In 1940, professional, managerial, clerical, and sales workers made up less than a third of the workforce. By 1970, that number had grown to almost 50 percent. Women filled many of these positions, especially low-paying clerical jobs.
