United States Employment Service (ES) characteristics related to recruitment and job search activities in 20 middle-sized American cities from July through December 1974 are described in this report based on interviews with approximately 600 employers and 2,000 job seekers. Part 1 covers employer recruitment and job search, focusing on the role of the ES. Part 2 covers the experiences, attitudes, and perceptions about the ES of user and non-user employers. A brief glossary of terms and expressions used in the report is included, as well as a 37-page precis of all principal findings. Findings presented include these: That the ES places high among formal methods used by job seekers; that it generally satisfies the needs of those who use it; and that among non-users, the reasons have more to do with the ease with which they find workers or jobs than with negative opinions. It is suggested that with an improved method to match those job seekers and employers who traditionally use the ES, a significant improvement in ES placements could be obtained without a corresponding increase in listings or applicants. Some tables are included in the text; the majority, along with the study design and methods, are in Volume 2, (the appendixes of this report). (TA)
