| A recent history of the Chicago
meat-packing industry and its workers examines how the industry grew from its
appearance in the 1830’s through the early 1890’s. Meat-packers, the author
argues, had good wages, working conditions, and prospects for advancement within
the packinghouses, and did not cooperate with labor agitators since labor
relations were so harmonious. Because the history maintains that conditions were
above standard for the era, the frequency of labor disputes, especially in the
mid-1880’s, is not accounted for. The work ignores the fact that the
1880’s were crucial years in American labor history, and that the packinghouse
workers! efforts were part of the national movement for labor reform.
