The employer may, at the request of certain employees, set up a system of individualised working hours allowing hours to be carried over from one week to another, within the limits and according to the procedures defined in articles L. 3121-51 and L. 3121-52, after receiving the assent of the social and economic committee. Within this framework, and by way of derogation from article L. 3121-29, hours worked during the same week in excess of the weekly working hours laid down by law or collective agreement are not considered as overtime, provided that they result from a free choice by the employee.
In companies without staff representatives, the labour inspector authorises the introduction of individualised working hours.
