Unlike the flesh-peddlers/placement counselors at most of the other private employment agencies in Manhattan, the Snelling and Snelling placement counselor/manager realized that screening out from permanent clerical jobs that only required a high school diploma job applicants in their 20's who were economically desperate college graduates--on the grounds that they would be "underemployed" and more likely to quit their jobs sooner than those job applicants who were only high school graduates--made no economic sense, in terms of generating Snelling and Snelling profits and more company-paid fees from her corporate clients.
So, instead of automatically telling the college graduates who walked into Snelling and Snelling's office that they were "overqualified" for the job oopenings she knew of and there were "no jobs for them"--like most of the other counselors at Manhattan's private employment agencies were telling the white liberal arts college graduates by the Fall of 1971--the Snelling and Snelling employment counselor/manager would tell you she could place you in a permanent clerical job--even if you were a liberal arts college grad; and she would then sell you to the business/corporate client who had a permanent clerical job slot to fill, obtain the clerical job for her young college graduate and collect her placement fee from the business firm/corporate client.
Or to put it another way: This experienced career woman in her 40's seemed to know how to place or peddle the flesh of any job applicant who walked into her office within the Fall 1971 labor market in Manhattan better than any other private or public employment placement officer/counselor/manager in New York City at that time.
