Job-hunting is something that you probably have done or will do more than once. Many workers change jobs either by choice or by necessity. Since most of toady’s new jobs are created in the service industries, many job-hunters will find service job o-penings. Service jobs include a wide range of positions, from nursing aids to stockbrokers. Although it may be fairly easy to get a service job,[7]it is often difficult to find career ladders and steps for working up to higher wages. Some service jobs, such as industry positions for nurses and cafeteria workers, pay fairly well from the start.[8]The problem with these jobs, however, is that they are disappearing. Because of the financial problems, many American companies are having not only factory workers but also the employees who serve them lose their jobs. Many job hunters are attempting to get jobs in the growing field of technology.[9]You may be among those who are taking classes to prepare for the level of education and working skills such jobs demand. The swift advances in a variety of fields, such as computer science and techniques, e-business, genetic engineering, space exploration, telecommunications and tele-education services, etc. , need well-trained personnel who are capable of frequent renewal of their knowledge and skills so as not to be eliminated in job-hunting competition.[10]Time spent in such classes is time well spent; even if this is your first job hunt, it probably will be your last.
