Although the unemployment rate remains high, 38 percent of employers say they cannot find qualified candidates for open positions, 34 percent say these job vacancies are causing the work quality to fall as employees are overworked, and 23 percent say it has caused revenue losses, according to a recent survey by CareerBuilder. 

Another 33 percent of respondents say vacancies have reduced morale while 17 percent of respondents are experiencing higher turnover within their organizations. 

"If we want to see more positive movement in the U.S. market, we have to do a better job of realigning the skills of our labor force with positions that are in high demand," says Matt Ferguson, CEO of CareerBuilder. "Prolonged vacancies can result in lower-quality work, lower sales and morale, and can cause a delay in creating other related positions within the organization.  Fortunately, we see more companies taking matters into their own hands and putting programs in place to retrain and transition workers into their industries and fields."
