Career is defined by the Oxford English Dictionary as a person's
"course or progress through life (or a distinct portion of life)". In
this definition career is understood to relate to a range of aspects of
an individual's life, learning and work. Career is also frequently
understood to relate to the working aspects of an individual's life e.g.
as in career woman.
A third way in which the term career is used to describe an occupation
or a profession that usually involves special training or formal
education, and is considered to be a person’s lifework. In this case "a career" is seen as a sequence of related jobs usually
pursued within a single industry or sector e.g. "a career in education"
or "a career in the building trade".
By the late 20th century, a wide range of choices (especially in the range of potential professions) and more widespread education
had allowed it to become possible to plan (or design) a career: in this
respect the careers of the career counselor and of the career advisor
have grown up. It is also not uncommon for adults in the late 20th/early
21st centuries to have dual or multiple careers,
either sequentially or concurrently. Thus, professional identities have
become hyphenated or hybridized to reflect this shift in work ethic.
Economist Richard Florida notes this trend generally and more specifically among the "creative class".
