Trade unions are workers' and professionals' organizations--the function, role, and responsibility of which echo the economic directives and decrees of the BKP. With the abolition of capitalist ownership declared by the Fifth Party Congress in December 1948, the structure and activities of trade unions changed to conform to the party's management of the economy as the vanguard of the state in its socialist development. Since then the Bulgarian trade unions have been reliable mainstays and faithful transmission belts of BKP policies among the working masses. Thirteen individual trade unions unite to form the Central Council of Trade Unions, which accepts the leading role of the BKP in all Bulgarian affairs. In 1973 total membership in the central council was about 2.6 million. Following the principle of democratic centralism, all trade union officials are elected from bottom to top but, following the pattern set by the BKP, all candidates for union offices are carefully screened and selected by officials at higher levels. Each trade union local is the basic organization unit at a factory or business enterprise, and there is an ascending hierarchical structure based on territorial organization. At the district level there is a district trade union that reports to the central organization. Theoretically, the trade unions are independent and nonparty, but they are organized hierarchically, and their activities are closely monitored and controlled by the BKP. In effect, the trade unions look after the interests of the state rather than the interests of the workers. To ensure party control there is an interlocking of positions in the highest realms of the unions, the government, and the party. For example, the chairman of the Central Council of Trade Unions in 1973 was also a member of the State Council of the National Assembly as well as being a candidate member of the Politburo. At lower levels many district and local trade union executives are also members of the district and communal people's councils. Under this arrangement the unions take a direct part in the management of state affairs--such as labor and labor legislation, recreational activities, workers' sports, and so forth.
