This booklet presents a method of teaching the history of labor unions in a creative and interesting manner. The labor pioneers presented in this booklet have been chosen with the thought that they would provide inspiration for young people who are studying the 300 years or more of Pennsylvania history. These laborers, who came from the ranks of the working people of Pennsylvania, organized and planned to provide for more dignity and more opportunity for working people. The format of each chapter is as follows: (1) a song, which could have been sung by the individuals featured in the chapter; (2) a story based on the life of the featured hero or heroine and a brief historical background of the period; and (3) discussion questions, activities, and sources. A cassette tape entitled"Sing a Song..." has been produced for use with this booklet. Labor pioneers featured include: (1) William Heighton; (2) William Sylvis; (3) John Siney; (4) Terrence Powderly; (5) Mary Hanaflin; (6) Mary Sterling; (7) Mother Jones; (8) William B. Wilson; (9) Benjamin Harrison Fletcher; (10) James Jones; (11) John Chorey; and (12) Mary Callahan. A glossary and teacher's notes follow the last chapter. (SM)
