Terrance Wise has two jobs in Kansas City — one at a burger joint, a second at a pizza restaurant — but he says his paychecks aren't enough to buy shoes for his three daughters and insure his 15-year-old car. So he decided to draw attention to his plight: He walked off work in protest.

Wise was among a few thousand fast-food workers in seven cities, including New York, Chicago and Detroit, who took to the streets last week, carrying "Strike" and "Supersize Our Wages" signs in front of McDonalds, Wendy's, Burger King and other restaurants. They demanded better pay, the right to unionize and a more than doubling of the federal minimum hourly wage from $7.25 to $15.

"We work hard for companies that are making millions," the 34-year-old Wise says, adding that he lost his home last year, unable to make mortgage payments despite working about 50-hour weeks at Pizza Hut and Burger King. "We're not asking for the world. We want to make enough to make a decent living. We deserve better. If they respect us and pay us and treat us right, it'll lift up the whole economy."
