Flexible working hours (flexitime) are a work-organisation system which facilitates day-to-day adjustments of individual working time and timetables in compliance both with the legal limits on working times and with rules to be adopted in advance in connection with any agreement on flexitime.
Save where exceptions are provided for by law, the working time may not exceed 10 hours per day or 48 hours per week.
Work organisation of this kind reserves to the employee the right to adjust his timetable and daily working time to suit his personal convenience, provided however that he respects the operational requirements and the clearly explained wishes of the other employees.
If, at the end of a reference period, the statement of hours worked indicates an excess of hours over and above the legally prescribed or contractual duration, that excess constitutes overtime, provided that the working of excess hours can be justified by operational reasons.
If the statement indicates a deficit of hours, that deficit must be regularised within a specified period, without giving rise to increments for hours of overtime, and in that regard the limits imposed by law must be observed, namely 10 hours per day and 48 hours per week.
For legal reference period whose duration is less than or equal to one month, the agreement on flexitime may determine a number of excess working hours which may be carried over to the following reference period.
