The period of any such absence shall be considered as vesting service.

(c) A period during which an employee is on a leave of absence approved by the state or otherwise granted pursuant to the terms of the appropriate collective bargaining agreement shall not be considered as a break in service.

(e) A member who is or has been granted a leave of absence without pay to pursue a course of study which is connected with the work of the agency and which is for the purpose of increasing his proficiency in his position may count up to four years of the period of the leave as vesting service and such leave shall in no event be treated as a severance from service.

(f) If an employee is absent from the service of the state due to a work-related injury or disease for which periodic workers' compensation cash benefits are payable, the period of such absence shall not count as a break in service and shall be considered vesting service.

(g) In no event will more than one year of vesting service be granted for any twelve calendar months.

If such member had received a lump sum payment, other than his contributions and interest thereon, from such other state or states in lieu of a retirement benefit, he shall not be eligible to receive credit under this subsection.
