Economic uncertainty topped a list of concerns expressed by more than 600 business owners in April, according to a survey by telecom provider Cox Communications.
Of those surveyed, half said they were "very concerned" about uncertainty. Government regulations were the second-biggest concern, at 47 percent, followed by energy costs at 40 percent.
The survey also revealed that 66 percent of business owners plan to take a week or more off for vacation this summer. Of those who said they won't, more than half said they didn't have enough revenue to justify the time off.
