Fixed number of working days : a scrupulous registration of working time is essential

In France, the legislator scrupulously (not to say severely) checks the validity of annual working days agreements.

Not only the condition of "real autonomy", which the employee must show to qualify for the forfait-jours, but also the strict supervision by the employer of the load and the distribution of work of the employee must be respected. 

It is necessary to have registration documents (time sheets) and it is obliged to organise an annual interviews. The absence of these can lead to the nullity of the forfait-jours.
