The permanent contract or CDI is the most usual form that employment contracts take.

When signed, a CDI does not give a maximum or minimum duration, or an end date.

As there is no end date, it can be terminated:

  • Due to force majeure (external to both parties)
  • By unilateral decision, either by employer or employee
  • By mutual agreement, using the process called a rupture conventionelle

It is not mandatory under the labour code to have a written contract, so a CDI can take the form of an oral agreement between employer and employee. However, the two parties usually agree on certain details that can only be confirmed by written agreement.

A use of written contract is highly advisable, and under most collective labour agreements it is actually mandatory to put CDI employment contracts in writing.

Therefore, the contract content and any clauses should be determined by both parties. However, clauses that contravene the law are forbidden (for example, remuneration that is lower than the SMIC or minimum wage, or any discriminatory clauses). This specification applies to all types of employment contracts.
