The files compiled from the data referred to in article R. 7343-3 are kept by the departments of the Employment Platforms Social Relations Authority for a period of one year after the close of the poll for which the files were compiled. After this period, the files are transferred to the national archives.
The departments of the Labour Relations Authority for Employment Platforms may, however, keep a copy of extracts from the anonymised files in order to carry out experiments for subsequent ballots and statistical studies.
