Fast-food workers are planning to go on strike again Thursday in 150 cities across America, demanding higher wages.

They will also be backed by home-care workers who are going to join the protest.

"They're going to use nonviolent civil disobedience as a way to call attention to what they're facing," Mary Kay Henry, president of the Service Employees International Union, which has spent millions of dollars helping to underwrite the campaign, told The New York Times. "They're invoking civil rights history to make the case that these jobs ought to be paid $15 [an hour] and the companies ought to recognize a union."

Employees from McDonald's, Burger King and Pizza Hut, among other large fast-food chains, will strike.

Dana Wittman, a 38-year-old Pizza Hut employee, relies on government money to make ends meet, despite her recent promotion from a chef to a shift leader. She now makes $9 an hour.

"The company should pay me more. I am worth more," Wittman told The Guardian. "They make billions a year, and I don't even get health insurance. The CEO gets health insurance."

However, fast food chains say the $15 an hour employees are asking for is an unrealistic wage compared to their profits.

Tomorrow's strike will be the seventh since fast food workers walked out of their jobs in New York in November of 2012. Each one of those strikes was bigger than the last.
