MIAMI (AP) _ Getting a burger and fries in Miami might take a little longer this week.

A group of fast-food workers is planning to walk off their jobs Thursday morning as part of a series of actions in cities across the U.S.

Workers in Miami want $15 an hour and the right to form a union without retaliation. Similar events are expected in Los Angeles, Boston, Minneapolis and other U.S. cities, as well as internationally. 

The fast-food protests began in 2012 in New York City. Workers say companies are no longer hiring teenagers earning summer spending cash, but are employing parents struggling to raise children on minimum wages.

In March, workers in several cities sued McDonald's for wage theft. McDonald's says it's looking into the allegations and will take any necessary actions.
