[I]f the universities are to render any such service toward the right solution of social problems in the future, it is essential that the scholars who carry on the work of universities shall not be in a position of dependence upon the favor of any social class or group, that the disinterestedness and impartiality of their inquiries and their conclusions shall be so far as humanly possibly beyond the reach of suspicions.

We cannot subscribe to dissenting Member Braems forecast of doom to medical education as a consequence of our decision today. We simply cannot say, either as a matter of law or as a matter of policy, that permitting medical interns, residents and fellows to be considered as employees entitled to the benefits of the Act would make them any less loyal to their employer or to their patients. Nor can we assume that the unions that represent them will make demands upon them or extract concessions form [sic] their employers that will interfere with the educational mission of the institutions they serve, or prevent them from obtaining the education necessary to complete their professional training. If there is anything we have learned in the long history of this Act, it is that unionism and collective bargaining are dynamic institutions capable of adjusting to new and changing work contexts and demands in every sector of our evolving economy. . . . To assume otherwise is not only needlessly pessimistic, but gives little credit to the intelligence and ingenuity of the parties.
