While there are many young professionals and graduates who break into the industry using recruiting agencies, there are also many experienced professionals who seek new jobs through such agencies. An experienced pilot may want to earn more money, take on a new challenge, or work for an airline that is in a better financial situation. A railroad engineer may want to move from smaller, commuter lines to larger national lines where opportunities are tough to come by for individual applicants. Safety and health professionals who have experience in inspections will often move from agency to private organizations in order to boost their pay. There may be some training sessions through recruiting agencies that are redundant for these professionals but they can customize their training experience by using their past work experience.
