This is a report of a study investigating the effects and characteristics of a social network on employment by exploring all kinds of relationships centering on one person, including kinship, friendship, association, and clientship. The study focuses on comparisons of social networks associated with 100 jobs of 31 people who graduated from a training program for data processors. The dual intent of the study was to ascertain differences between the network sets of people who were satisfied or unsatisfied on their jobs and between sets associated with people who had stable and unstable job histories. Detailed statistical analyses accompany the text. The authors did not find expected differences between happily and unhappily employed people. The study also concludes that sets associated with jobs found by informal contacts are different from those jobs found through institutional contact or personal public knowledge. There were no significant differences between sets for those with "chaotic" job leaps or "orderly" careers. The report contains a 53-item bibliography and the Minnesota Satisfaction Questionnaire.
