1970s, however, it has seen its membership base slowly dry up and its allied organizations disappear or distance themselves from the party. The PCF claimed 520,000 members in 1978; 330,000 in 1987; 270,000 in 1996; and 133,000 in 2002. In 2008, the party claimed that it had 134,000 members of which 79,000 were up to date on their membership fees. In the 2011 internal primary, 69,277 members were registered to vote and 48,631 (70.2%) did so. The party likely has about 70,000 members as of today, but only about 40 to 50 thousand seem to actively participate in the party's organization and political activities. According to studies by the CEVIPOF in 1979 and 1997, the makeup of the PCF's membership has also changed significantly since 1979. The most marked change was a major decline in the share of manual workers (ouvriers) in the party's membership, with a larger number of employees and middle-classes, especially those who work in the public sector. The form of political action taken by members has also changed, with less emphasis on direct political or electoral action but a greater emphasis on social work and protests. The party's structures were democratized at the 1994 Congress, dropping democratic centralism and allowing for the public expression of disapproval or dissent with the party line or leadership. The party's top posts, like that of 'secretary-general', were renamed (secretary-general became national-secretary). The party, since 2000, is now led by a national council, which serves as the leadership between congresses; and the executive committee, which is charged with applying the national council's decisions. The national-secretary is elected by delegates at the congress. Likewise, the national council is elected by list voting at every congress. A reform of statutes in 2001 has allowed "alternative texts" - dissent from the text proposed by the PCF leadership - to be presented and voted on; dissident lists to those backed by the leadership may also run for the national council. The General Confederation of Labour (CGT) was dominated by the PCF after 1946, with almost all its leaders between 1947 and 1996 (Benoît Frachon, Georges Séguy, Henri Krasucki, Louis Viannet) also serving in the PCF's national leadership structures. For years, the CGT and the PCF were close and almost indissociable allies - notably in May 1968 when both the CGT and PCF were eager for a restoration of social order and welcomed the Grenelle agreements.
