In the absence of an agreement as provided for in Article L. 3121-44, the working time of the company or establishment may be organised in the form of work periods, each of a duration at most equal to the durations laid down in Article L. 3121-45.
The employer draws up the indicative programme for the variation in working hours. Before it is implemented for the first time, this programme is submitted to the social and economic committee, if there is one, for its opinion.
The social and economic committee, if any, is also consulted on any changes to the programme of variations.
At least once a year, the employer provides the social and economic committee with an assessment of the implementation of the indicative programme of variations in working hours.
Employees are notified of changes to their working hours at least seven working days before the date on which the change takes place.
