When JWT pitched job opportunities to men straight out of college, it talked about specializing in copywriting, public relations, art, television and radio, etc.
Jobs "open to women," however, began with membership in the "General Staff" group, which meant new women would work under the personnel department and "substitute for other girls who may be ill or on vacation."
Although women got to work in the different sections of the company, they were often a "right hand to a busy executive" or "secretary to one of the senior analysts," and of course needed good typing and shorthand skills.
