The time required for the performance of their duties by the trade union representatives mentioned in 2° and 3° of article L. 2315-7 is set within limits which, save in exceptional circumstances, may not exceed twenty hours per month.
Unless there is a collective agreement to the contrary, when the representatives mentioned in the first paragraph are employees mentioned in article L. 3121-58, the credit for hours is grouped into half-days which are deducted from the annual number of days worked set in the employee’s individual agreement. A half-day corresponds to four hours of office.
When the credit of hours or the fraction of the credit of hours remaining is less than four hours, the representatives mentioned in the previous paragraph who benefit from it in respect of the hours added up over the year as provided for in article R. 2314-1 have a half-day which is deducted from the annual number of days worked set in the employee’s individual agreement.
