Seventy-two percent of employees believe that getting trained in a specific skill is more highly valued by their employer than a degree, according to survey results released today by Glassdoor, a job listing site.

The results are from a survey of more than 2,000 adults and part of Glassdoor's second-quarter Employment Confidence Survey.

"Employees with college degrees believe that their education helped get them through the door, but about half say it has no relevance to the work they're actually doing," said Rusty Rueff, Glassdoor's career and workplace expert, told CNNMoney.com.

Also, 74 percent of employees believe that their employers value work experience and related skills more than education when evaluating job candidates, and 80 percent say they've never been asked about their college GPA during a job interview.

That highlights the importance of learning new skills within the company and through continuing education such as certificate programs or online training, Rueff said.

Another story on NPR today lays out the challenges that people ages 16 to 24 face in gaining employment, as in some places the unemployment rate in that group is double the national rate of 6.3 percent.

Elisabeth Jacobs, senior director for policy and academic programs at the Washington Center for Equitable Growth, told NPR that employers play a "cruel game of musical chairs" in which people with more education or experience can't get jobs, and they are instead going after positions that require fewer skills, taking away jobs from less-educated people.
