I.-The employer may defer the granting of the career transition leave requested by an employee:
1° When it considers that the absence of the person concerned could have consequences prejudicial to the production and running of the company. Such a postponement is decided for a maximum period of nine months, after consulting the social and economic committee where this exists;
2° In order that:
a) In an establishment with 100 employees or more, the percentage of employees simultaneously absent on career transition leave does not exceed 2% of the total workforce;
b) In an establishment with fewer than 100 employees, only one employee at a time may take career transition leave;
The provisions of this 2° do not apply to an employee whose employer refuses two successive requests for a period of voluntary mobility pursuant to Article L. 1222-12.
II – Reasons must be given for any decision by the employer to defer the leave.
III -I does not apply to employees who hold a contract of employment with a temporary employment agency. The latter may, however, defer the benefit of the professional transition leave requested by the employee when the request for leave and the start of the training action occur during the same assignment, with the exception of the following cases:
1° The purpose of the professional transition project is to acquire a qualification in a different sector of activity;
2° The professional transition project lasts more than 1,200 hours.
