About a century has passed since the events at the center of this lesson-the Haymarket Affair, the Homestead Strike, and the Triangle Shirtwaist Factory Fire. In this lesson, students use primary historical sources to explore some of the questions raised by these events, questions that continue to be relevant in debates about American society: Where do we draw the line between acceptable business practices and unacceptable working conditions? Can an industrial-and indeed a post-industrial-economy succeed without taking advantage of those who do the work?

Test the arguments on both sides in the case that shook the foundations of faith and science.
