'Is it safe to hire?' Business owners don't trust recovery

The economic recovery may be continuing, but small business owners aren't ready to put the rose-colored glasses back on.

According to an exclusive CNNMoney-Manta survey released Tuesday, 28% of small business owners said the economy is the "biggest challenge" they're currently facing, topping issues like sales, regulations and financing.

The survey polled over 1,500 small business owners across the country. Even those experiencing revenue growth are hesitant to test their luck.
