The written employment contract should be drafted in French Language. When the employee has foreign nationality, the written contract of employment should be translated into the language of the employee upon the latter’s request.
The employment contract does not necessarily have to be in writing except for certain specific contracts such as fixed-term contracts, part-time contracts, temporary contracts (with temporary employment agencies), contracts of employment for casual workers, contracts with home workers etc. That said, it is generally strongly recommended to put in writing the terms of the employment relationship to avoid the difficulties relating to evidence.
