A career includes career opportunities that can be identified with a particular job or profession , having multiple careers is the growing trend in the late 20th century and early 21st century. These multiple careers can be competitor or sequential (where a worker adopts a new career after having worked for some time in another career). Both may occur for different reasons.
Sandra Kerka (2003) reports that “‘studies in the United States at the end of the seventies already showed that between 10 and 30 percent of the economically active population had a change in a 5-year period’ (Teixeria & Gomes, 2000, p.78) Of 91 skilled young adults in Germany, only one-third had continuous care in the first 8 years after graduation and was half-employed in other occupations at least once (Heinz 2002). provides an indirect clue: Townsend (2003) found that 62% of bachelor’s degree holders who are enrolled in a career exchange. ” 
Concurrent multiple careers
Workers with multiple competitor careers adopt a “hyphenated” professional identity. A “teacher-painter” might Refer to an individual Who works for nine months out of the year as an Elementary School Teacher and three (summer) months out of the year as a painter . A “doctor-potter” could refer to an individual who works as an ENT- physician during the day, but works within a ceramics studio at night. Some consider the hyphen “- homemaker ” or “- caregiver ” as suggestive of another type of concurrent multiple career worker. That is, a “lawyer-homemaker” works as attorneyand is also in charge of domestic duties at home. Increasingly, the “X-caregiver” worker has emerged – where a worker completes the tasks of career-X and simultaneously cares for the needs of children and elders. Some note that many members of the working class have long been competitor workers out of economic necessity. A quarter of the British workforce works like this.
Workers can adopt multiple competitor careers for a host of reasons such as economic (such as poverty or striving for additional wealth), educational (such as multiple degrees in multiple fields), or personal (such as interest or lack of fulfillment in one career) . Economist, Richard Florida , among others suggests that some “hyphenates” pursue multiple competitor careers in order to fulfill creative needs. A “doctor-potter,” for example, may be pursued as a creative and professional development.
Author and New York Times columnist Marci Alboher One of the multiple careers in the book One Person / Multiple Careers: A New Model for Work Life Success (2007). Instead of hyphenation, Alboher uses slash to demarcate multiple competitor careers, as in “art dealer / yoga instructor” or “baker / comedian / web designer”.
Sequential multiple careers (smc)
Workers with sequential multiple careers adopted a changing professional identity over time. Thus, a worker may devote 10-20 years of his / her life to a career related career or an entirely new one. As life-expectancy increases, it becomes more and more important. Somewhere in the world, and others in this world, and others in the world of economics and social reality.
