In the heart of the Great Depression, millions of American workers did something they'd never done before: they joined a union. Emboldened by the passage of the Wagner Act, which made collective bargaining easier, unions organized industries across the country, remaking the economy. Businesses, of course, saw this as grim news. But the general public applauded labor's new power, even in the face of union tactics that many Americans frowned on, like sit-down strikes. More than seventy per cent of those surveyed in a 1937 Gallup poll said they favored unions.
