The Southeastern Wisconsin Workplace Communication Project is a workplace English-as-a-Second-Language (ESL) resource and outreach program involving a partnership of businesses and adult educators in a rural area that has experienced an increase in new speakers of English in the manufacturing workforce. The guide provides workplace educators and administrators with information on a participatory approach to ESL programming and curriculum development. It consists of a case study of organizational language needs and services in a local business employing 700, about 65 percent of whose employees at one plant are non-native English-speakers. The four-step guide instructs the user to alternately read portions of the case study and follow directions to conduct an organizational needs assessment, implement participatory curriculum development for workplace ESL instruction, develop instructional materials, and conduct learner assessment.
