This study illustrates how a union education center successfully integrated adult empowerment education principles into the teaching methods and curriculum of a health and safety training program. The 12-month follow-up phone survey involved 481 local union respondents each representing a separate plant site and a group of 50 manager trainees. The evaluation shows that the training manual continued to be used by more than 70% of respondents, more than 70% taught coworkers, more than 50% of union trainees went on to train their managers, and more than 90% identified problems at work and sought and obtained changes in programs, training, or equipment. More than 20% reported that major spills had occurred following training. The majority stated that the handling of the spills improved. More than 80% stated that the training better prepared them for their health and safety duties. The managers' data substantially supported union members' reports.
