In the high school history textbooks children read, too often they find that labor's role in American history--and labor's important accomplishments, which changed American life--are misrepresented, downplayed, or ignored. That is a tragedy because labor played (and continues to play) a key role in the development of American democracy and the American way of life. This article examines four high school textbooks developed by some of the leading publishers in the country: (1) "The American Vision," published by Glencoe/McGraw-Hill in 2010; (2) "American Anthem: Modern American History," published by Holt, Rinehart, and Winston/Harcourt in 2009; (3) "United States History," published by Prentice Hall/Pearson in 2010; and (4) "The Americans," published by McDougal Littell/Houghton Mifflin in 2009. Together, these books represent a significant percentage of the purchasing market for high school history textbooks. This review of high school history textbooks finds spotty, inadequate, and slanted coverage of the labor movement. Such coverage shortchanges students by not giving them a full and accurate account of labor history and the struggles of citizens acting collectively to bring about social progress and change.
