AF sends Riesel a guest column in which he relays the reasons for the RPP and the history of its battle to be implemented. "Is the Philadelphia Plan a union busting device? No. The present problem has been created by the failure of a number of construction unions to represent minority workers or to allow them to join locals. The answer for the unions is to organize this labor supply, let minorities in and allow them to participate. More Philadelphia-type plans are an alternative. Other alternatives are to have all black unions or to encourage black contractors to do more and more Federal construction work. These black contractors are largely non-unions [sic] simply because the locals will not accept their empoyees as members."
