NEW YORK — Fast-food protests are planned for several U.S. cities today as labor organizers look to bring attention to practices they say illegally deprive workers of their wages.

The protests are planned for about 30 cities, but it’s not clear what the scope of the turnout will be. It’s part of an ongoing campaign by labor groups to build support for pay of $15 an hour and bring attention to the rights of low-wage workers.

Organizers have also been referring workers to attorneys, who filed lawsuits in three states last week saying McDonald’s was stealing their wages in a variety of ways, such as by docking paychecks for the cost of their uniforms.

McDonald’s Corp. said it planned to investigate the allegations and take necessary actions. A representative for the company did not immediately respond to a request for comment.
