This handbook reviews displaced worker and community experiences to identify traumatic areas of concern and, thereby, to propose strategies for other communities should they face similar crises. Part 1 focuses on preventing a plant closing. Indications of plant closure are discussed as well as a pre-closure intervention model to reduce unemployment. Options for the company to pursue in eliminating the need to close are reviewed, and possible types of assistance and incentives available at each level of government are outlined. Working with unions is also considered. Part 2 addresses the reduction of trauma for displaced workers. Issues for the individual involved in the closure are first described. Research data about the displaced workers from two Des Moines, Iowa, plants are reported, and four case studies are presented. Nineteen options the company could consider to assist displaced workers are outlined. One community structure to deal with plant closings and layoffs--a mayor's task force--is then discussed. Procedures in designing and implementing a task force are delineated. Materials from a Des Moines task force are included. A listing of benefits and assistance available to displaced workers is followed by a detailed look at 10 steps in a retraining program for displaced workers. (YLB)
