France: The condition of validity for collective agreements changes on May 1 , 2018
The labor law of 8 August 2016 provided for the gradual entry into force of the majority conditions of collective labor agreements: since 1 January 2017, agreements on work hours, rest and holidays must be signed by one or more representative unions with more than 50% of the votes cast in favor of representative unions. This majority requirement was to be extended to all agreements as of September 1, 2019. One of the Macron Ordinances has moved up this generalization to May 1, 2018.
Agreements signed by representative unions that have received between 30 and 50% of the vote will be valid if they are approved by a majority of the employees.
