NEW YORK - Fast-food workers are planning a nationwide strike for higher pay next week. 

Employees at a number of fast food chains, including McDonald's and Burger Kings, are expected to walk off the job next Thursday. They're fighting for a $15 an hour wage and the right to form unions. 

Workers in three states also filed class-action lawsuits earlier this year against McDonald's over raises. 

A recent report in Business Week shows that the fast-food industry has the largest disparity in pay between workers and CEOs.
