Last month, Governor Scott Walker of Wisconsin signed a bill that will help to protect fast-food companies from labor conflicts that happen within their franchises. The law prevents courts from applying the same logic imposed by the NLRB that makes corporations more liable for activities in its franchised locations. So far seven states have passed similar laws, which jeopardizes the NLRB's attempts to make large food corporations more accountable for the activities that happen in its restaurants.
