When, exceptionally, an associate practitioner has not been able to use all the days of leave mentioned in 1° and 2° of I of article R. 6152-914, he may ask to benefit from the opening of a time savings account. The opening of this account is authorised by the director of the host establishment, after obtaining the opinion of the head of department. The provisions of articles R. 6152-803 to R. 6152-813 then apply. At the end of the skills consolidation programme or the adaptation period, the days entered in the time savings account for this period but not used by this date are compensated by the establishment to which the associate practitioner is assigned under the conditions set out in article R. 6152-807-3.
