Dougleshia Nicholson is a single mother of six trying to survive on minimum wage in Kansas City, Missouri. One of her sons has asthma, and she estimates she's been to the emergency room for her kids six or seven times so far this year. But her cashier job at Church's Chicken doesn't come with paid time off and every shift is essential.

"It's stressful because I basically have to pick and choose what's more important," Nicholson tells CNBC Make It. "Of course my child is more important, but at the same time, I have to work and make money to be able to support and take care of them."
