When the Federal Government contracts for goods or services, it has a proprietary interest in ensuring that those contracts will be performed by contractors whose work will not be interrupted by labor unrest. The attainment of industrial peace is most easily achieved and workers' productivity is enhanced when workers are well informed of their rights under Federal labor laws, including the National Labor Relations Act (Act), 29 U.S.C. 151 et seq. As the Act recognizes, "encouraging the practice and procedure of collective bargaining and . . . protecting the exercise by workers of full freedom of association, self-organization, and designation of representatives of their own choosing, for the purpose of negotiating the terms and conditions of their employment or other mutual aid or protection" will "eliminate the causes of certain substantial obstructions to the free flow of commerce" and "mitigate and eliminate these obstructions when they have occurred."

A carryover work force reduces disruption to the delivery of services during the period of transition between contractors and provides the Federal Government the benefits of an experienced and trained work force that is familiar with the Federal Government's personnel, facilities, and requirements.
