This guide is designed to serve as a reference for community leaders in identifying key sources of support and actions to consider taking in the event of a prospective or actual mass layoff in their community. The guide is divided into four separate checklists of suggested actions. The first, and most detailed, section is directed to mayors, county commissioners, and other city or county chief executives. Other sections contain checklists for officials of plants laying off workers, union officers representing these workers, and managers of employment service offices in the area. Each section lists the government programs that provide specific types of assistance and refers readers to specific items in the appendix. These appendix items give more detailed information on each program, including who qualifies for benefits or services; how to apply for them; and names, addresses, and telephone numbers of organizations to contact for aid.
