Career Wisdom: The job market fluctuates constantly, what is hot today could be cool tomorrow. FACT: Employment opportunities change dramatically as a function of economic conditions, advances in technology, and the labor supply. Although projections are available from information resources there is an inevitable lag time between the demands for certain occupations and the response to this demand. College students who decide they want to go into a profession primarily because of an increased opportunity may be disappointed after years of training because they are competing with thousands of other people who had the same idea. The job market becomes flooded, and the supply now exceeds the demand. This kind of changing demand and supply situation can happen with any occupation. Nonetheless, job outlook trends can be useful information if its not the only factor in your career choice.
