Article 158 of the French Act of December 24, 2019 sets out the principle of the automatic transfer of staff from state-controlled entity RATP in the event of another entity taking over the service. For passenger transport services within the scope of OPTILE, article 158 specifies that the terms and conditions of the transfer of contracts of employment are to be governed by a branch agreement.

What are the implications in terms of obligations, procedures, and deadlines for companies? What kind of difficulties may companies encounter?
