Such a union shall be established by means of a press statement containing the identity of three (3) principal leaders. The legal existence of a trade union is subject to prior declaration at the Ministry of Public Freedoms and to compliance with the provisions of the labour code or any other legal text in lieu of or in reference thereof”.

These negotiations are generally held within the framework of the development of collective agreements and establishment Agreements and of the Labour Advisory Commission. Furthermore, there is a negotiation framework between the government and the unions. The Labour Advisory Commission has been created at the Ministry of Labour. It is made up of an equal number of employers and workers appointed by the employers and workers’ organizations with the highest representation or by the Ministry of Labour in the event of lack of representative organisations pursuant to Article 302 (3) of the Labour Code. The Labour Advisory Commission may be consulted on all labour-related issues, on the labour force and social security in addition to cases where its opinion is automatically required. 40
