Its origins, however, go back to the early 1970s, to when the equal rights amendment, ERA, was placed before the states for ratification (March 1972). At that time, the term was used to denote secretarial and steno - pool staff as well as non-professional office staff, all of which were largely held by women . De rigueur, these positions were not white - collar jobs, but neither were they blue - collar manual labor . Hence, the creation of the term "pink collar," which indicated it was not white - collar but was nonetheless an office job, one that was overwhelmingly filled by women . </P> <P> Pink - collar occupations tend to be personal - service - oriented worker working in retail, nursing, and teaching (depending on the level), are part of the service sector, and are among the most common occupations in the United States .
