Among other barriers to growth, a majority of private-company CEOs are worried about a dearth of qualified employees, a recent survey found.

Out of more than 100 CEOs polled, 64 percent said they were somewhat or extremely concerned about the availability of skilled workers, while over half said they have taken steps to boost recruiting and job retention efforts, according to PricewaterhouseCoopers.

Compounding their concerns are the rising costs of employee benefit packages and ramped up competition from public companies with equity-based compensation programs, the survey found.

Other barriers to growth cited by respondents included low-cost competition, high energy prices, over-regulation, commodity prices, and terrorism.
