Any provision contained in a contract of employment, a collective labour agreement, a wage agreement, a regulation or a wage scale resulting from a decision by an employer or an employers’ association and which, contrary to Articles L. 3221-2 to L. 3221-6, provides for lower pay for one or more employees of one sex than for employees of the other sex for the same work or work of equal value, is automatically null and void.
The higher remuneration received by the latter employees is automatically substituted for that received by the invalid provision.
