Hundreds of workers from McDonald's, Taco Bell, Wendy's and other fast-food chains are expected to walk off their jobs Thursday, according to labor organizers of the latest national protest to push the companies to pay their employees at least $15 an hour.

This time organizers said they plan to engage in civil disobedience, which could lead to arrests, and draw more attention to the cause. They also said home-care workers will join the protests, which are expected to take place at fast-food restaurants in 150 cities nationwide.

The "Fight for $15" campaign, which is backed financially by the Service Employees International Union and others, has gained national attention at a time when the wage gap between the poor and the rich has become a hot political issue.
