The CNT-NAR has a three-tier institutional structure, consisting of the Plenary Council, the Executive Board and the Committees. A Secretariat provides logistic and administrative support.
The CNT-NAR executive board is chosen by the council and made up of 10 members (the President, four vice-presidents, four councillors and the Secretary). Its role is to set the agenda for the council's work, to prepare the examination of agenda items, to define procedure, to monitor the implementation of the council's decisions and to submit annual budgetary proposals to the council. The executive board meets every month.
The actual work of the CNT-NAR is carried out by the committees, whose tasks are decided by the executive board. The council's members and substitute members participate in committees works and can use the help of experts.
The quasi-permanent working committees are: the Enterprise Councils Committee, the Individual Labour Relations Committee, the Collective Labour Relations Committee, the Social Security Committee and the International Labour Organisation Committee.
Given the competencies of the Central Council for the Economy, when issues of common interest with the Central Economic Council are examined, joint committees are set up, to whose meetings members of the two councils and experts are invited.
