An employee may within 90 days of the effective date of such separation file a written request with the State Personnel Board for reinstatement. If the appointing authority has notified the employee of his automatic resignation, any request for reinstatement must be in writing and filed within 15 days of the service of notice of separation. Notice may be personally served or it may be served by mail to the last known residence or business address of the addressee and is complete on mailing. Proof of service, either personal or by mail, shall be made by affidavit. Reinstatement may be granted only if the employee makes a satisfactory explanation to the board as to the cause of his absence and his failure to obtain leave therefor, and the board finds that he is ready, able, and willing to resume the discharge of the duties of his position or, if not, that he has obtained the consent of his appointing power to a leave of absence to commence upon reinstatement.
Any employee so reinstated shall not be paid salary for the period of his absence or separation or for any portion thereof.
