Those provisions of the decrees provided for in article L. 3121-67 relating to the organisation and distribution of working hours within the week, rest periods, the conditions for recourse to standby duty and the arrangements for recovering lost working hours where the law allows such recovery may be derogated from by agreement or extended collective agreement or by company or establishment agreement.
In the event of denunciation or non-renewal of these collective agreements or arrangements, the provisions of these decrees from which derogations have been made become applicable again.
