44.2. During the delay, an employee may require the payment of his pension, in whole or in part, but only to the extent necessary to compensate a reduction of salary or wages incurred during that period.
In no case may an employee apply under this section more than once within a twelve-month period except by agreement with the administrator of the supplemental plan.
However, after an agreement with his employer, and if the supplemental plan provides therefor, an employee may receive the whole or a part of the pension irrespective of the restriction provided in the first paragraph.
