You might want to stock up on McNuggets now: The Service Employees International Union and the United Food and Commercial Workers are targeting the McDonald’s, Wendy’s and KFC chains, among others, in a planned employee walkout set for August 29.

The effort is being organized through a union-backed group called Fast Food Forward. The protests are meant to highlight the unions’ demands that chains pay the workers $15 an hour. Most fast-food chains currently pay minimum wage.

The activists have aded a new twist to the argument: Since many fast-food workers are on some form of public assistance, that means taxpayers are subsidizing the chains’ payrolls. United Steelworkers President Leo Gerard sums up the argument here.

My Washington Examiner colleague Phil Klein makes the case against a higher minimum wage here.
