 Keeping the new hires and quickly leaving the company is another. Turnover remains a major issue. In many industries, between 10 and 25% of new hires may leave within the first six months. That's true for blue and white collar jobs, from high school grads to PhDs. The reason is that many workers find the job is not what they expected. It's not as interesting or glamorous, or it's much harder or more boring than they were led to believe. The situation is costly and frustrating for both sides.
