This guidebook provides practical information to assist state and local aging agencies in developing strategic relationships with businesses in their communities. It focuses on the experiences of those state agencies and Area Agencies on Aging that are actively working with local employers and it presents a framework for other agencies. The book is divided into five chapters. Chapter 1 gives an overview of public/private partnerships in employer-sponsored eldercare, and lists some of the reasons for the interest that companies and employees exhibit in eldercare activities. Chapter 2 shows how to build support for employer-sponsored eldercare through briefings for business leaders, committee work, and other strategies. Chapter 3 looks at the role a state association can play in bringing consistency to product and service development and the cost savings in centralizing marketing responsibilities. Chapter 4 discusses an approach for identifying an agency's strengths and capabilities and offers sample copy points that can be adapted for use in various marketing materials. Chapter 5 explores the function of a business plan, both as an internal management tool and as a document that can help attract funding support. A sample plan for guiding an agency through this process is presented. (RJM)
