To obtain the agreement mentioned in article L. 3142-89, the reservist employee shall submit his request in writing to his employer, indicating the date and duration of the planned absence. In the absence of a response from the employer within the notice period mentioned in articles L. 3142-94-2 and L. 3142-94-3, his agreement is deemed to have been reached.
When the available military resources appear to be insufficient to respond to specific and unforeseen circumstances or requirements, the notice period provided for in the first paragraph of this article may, by order of the Minister of Defence or the Minister of the Interior for reservists from the national gendarmerie, be reduced to fifteen days for reservists who have signed, with the employer’s agreement, the reactivity clause provided for in the eighth paragraph of article L. 4221-1 of the Defence Code.
