An agreement or an extended branch agreement sets the minimum working time referred to in Article L. 3123-7. Where it is less than that provided for in Article L. 3123-27, it shall determine the guarantees regarding the implementation of regular working hours or allowing the employee to combine several activities in order to achieve an overall duration of activity corresponding to full-time work or at least equal to the duration referred to in Article L. 3123-27.
A company or establishment agreement or, failing that, an extended branch agreement or convention determines the terms and conditions under which the working hours of employees who work less than the minimum working hours stipulated in article L. 3123-27 are grouped into regular or full days or half-days.
