About 200 laborers of the stockyard district met yesterday to organize a Union. The corner of 36th St. and Halsted, at Union Hall, marked the site of their endeavor. Herman Kratak functioned as chairman. English, German, Bohemian representatives were elected and approximately 100 workers initiated, whereupon they formulated a constitution and by laws in a secret session. An especially important phase was the eight hour work limit period, which is the goal of the organization.
