Reservist customs officers sign a contract of employment for a period of between one and five years, which sets out their obligations in terms of availability and initial and ongoing training, and which confers on them the status of occasional collaborators in the public service.
The contract specifies the duration of the assignment, which may not exceed ninety days per year.
The administration may order the removal from the operational reserve in the event of a breach of the obligations set out in the contract of engagement or if it appears, where applicable after an administrative investigation which may be carried out under the conditions set out in I of article L. 114-1 of the Internal Security Code, that the behaviour of the reservist customs officer has become incompatible with the performance of his duties. This contract may also be terminated or suspended in the event of a breach where the reservist customs officer ceases to fulfil the conditions laid down in this chapter or in the event of a public order requirement.
