Democratic Structures

The executive committee of the CSN

Between congresses, the Executive Committee assumes the direction of the Confederation and sees to applying the mandates voted upon by the union’s governing bodies: the Congress, the Confederal Council, and the Confederal Board. The Executive Committee is composed of six positions: the president, the general secretary, the treasurer, and three vice-presidents.

Members of the CSN’s Executive Committee have different responsibilities as defined in the articles and by-laws, and share the mandates decided by the governing bodies. They are responsible for the CSN’s smooth operations, particularly its finances, various governing bodies, staff, and union services.

À Propos de la CSN

Fondée en 1921, la CSN est une organisation syndicale qui œuvre pour une société solidaire, démocratique, juste, équitable et durable.

Elle est composée de près de 1 600 syndicats et regroupe plus de 330 000 travailleuses et travailleurs réunis sur une base sectorielle ou professionnelle dans huit fédérations, ainsi que sur une base régionale dans treize conseils centraux, principalement sur le territoire du Québec, mais également sur l’ensemble du territoire canadien.

   Se solidariser, ensemble, peu importe notre revenu, notre emploi ou notre champ de compétence, c’est soulever une lame de fond qui influence les politiques et change concrètement la qualité de vie de tous les membres et de l’ensemble de la société. C’est ça, pour moi, la CSN.
