For the application of the provisions of articles L. 2333-64 and L. 2333-65, account is taken, as provided for in article R. 130-2 of the Social Security Code, of the employees assigned within each establishment located in each zone where the payment intended to finance mobility services is instituted, except in the following cases:
1° For employees holding an assignment contract with a temporary employment company or an employment contract with an employers’ group, the place where they carry out their assignment or activity in each of the zones where the mobility payment is instituted is taken into account ;
2° For other employees who carry out their activity away from an establishment of their employer, account is taken of the place where this activity is carried out for more than three consecutive months in each of the zones where the mobility payment has been introduced;
By way of derogation, employees assigned to the vehicles of road or air transport companies who carry out their activity principally outside a zone where the mobility payment has been introduced are excluded from the determination of the workforce used to calculate this payment.
