A new Wells Fargo survey finds small business optimism running very high so far this year. But many small businesses say their biggest challenge is hiring.

About 1 in 3 small businesses say they will do hiring in the next year. Wells Fargo Senior Vice President Chantal Capodicasa says, "It is a great time to be a job seeker, and they are definitely looking for qualified people. so there is a lot of optimism out there."

But Capodicasa says a lot of small business people struggle to find good hires, especially drivers and skilled tradespeople, among others.

"We see the health care industry having a rising demand for nurse/practitioners and physicians. So you see practices either consolidating or multi-specialty practices are growing in order to be a little bit more efficient or competitive with the decreasing reimbursement rates."

Plumbing and electrical trades, which require special schooling, also have a high demand.

She says the new influx of recent grads will deepen that hiring pool.

"It is graduation time and a great time to be looking for positions. And some of the growing demand in New Jersey particularly is around distribution and transportation positions that are becoming available."
