VILLA PARK, Ill. — Fast food workers from across the country have voted in suburban Chicago to escalate their campaign for higher wages and union representation by including civil disobedience.

More than 1,300 workers gathered Saturday in Villa Park, Illinois. They voted to add sit-down strikes and restaurant occupations to their campaign to win $15-an-hour wages and a union.

Industry officials say a $15-an-hour wage would hurt job creation, and that the solution is more education and job training.

The workers’ effort is supported by the Service Employees International Union. Their actions so far have included strikes and a protest outside this year’s McDonald’s shareholder meeting.
