To give what is perhaps the most underappreciated of all benefits its due, there is now a booklet available called "A Look at Social Security -- 1989." It is prepared and published by A. Foster Higgins & Co., an employee benefits consulting firm.

The easy-to-read publication clarifies the fine print of payments and privileges and includes worksheets and a form your employees can use to request a personal benefit estimate from the federal government. It's a real bargain for four bucks. Write: Lisa Bell, A. Foster Higgins & Co., 125 Broad St., New York NY 10004.
