Labor's status is the subject of what seems to be an interminable war, with campaigns in the courts, on picket lines, in conference rooms, and in legislative halls. The prominence of these battles increases, if anything, the obscurity in which a closely related conflict is being worked out. For as long as there are important distinctions to be made on the basis of whether an employment relation exists, there is fairly certain to be at least some argument over the existence of that relation.
