The Federation of Education, Research and Culture (French: Fédération de l'éducation de la recherche et de la culture, FERC) is a trade union representing workers in education and related industries, in France.
When the FEN chose to become independent, 39% of its members voted to remain affiliated to the CGT.
As a result, the FEN decided to permit dual affiliation.
[1] By 1949, the federation had 14,000 members, but in 1954, under the influence of the French Communist Party, it decided to campaign against dual affiliation, in the hope that this would encourage more teachers to fully commit to the federation.
This almost caused the collapse of the federation, with its general secretary resigning, and the secretariat ceasing to meet.
