David Cramb, from Barry, was one of more than 3,000 people at a jobs fair in Cardiff yesterday.
He is a full-time van driver, but also does bar work to earn more money.
He says he has worked 22 hours a day at times, but added: "It does affect the quality of your life - come the weekend you've got no energy to do anything."
David is looking for more part-time work, as money is tight.
"We're surviving," he said. "It's paying the bills, buying food, and that's about all we can cover at the moment."
