The graph below depicts the number of American workers involved in work stoppages between 1900 and 1970. Most of the workers went out on strike against their employers. During some labor conflicts, however, owners and managers locked workers out of factories, and those figures are included here as well. Note that data from the years 1906 to 1926 is unavailable.
