(A) As used in this section and section 3307.352 of the Revised Code, “other system retirant” means either of the following:

(1) A member or former member of the public employees retirement system, Ohio police and fire pension fund, school employees retirement system, state highway patrol retirement system, or Cincinnati retirement system who is receiving from a system of which the retirant is a member or former member age and service or commuted age and service retirement, a benefit, allowance, or distribution under a plan established under section 145.81 or 3309.81 of the Revised Code, or a disability benefit;

(2) A person who is participating or has participated in an alternative retirement plan established under Chapter 3305 of the Revised Code and is receiving a benefit, allowance, or distribution under the plan.

(B) Subject to this section and section 3307.353 of the Revised Code, a superannuate or other system retirant may be employed as a teacher.

(C) A superannuate or other system retirant employed in accordance with this section shall contribute to the state teachers retirement system in accordance with section 3307.26 of the Revised Code and the employer shall contribute in accordance with sections 3307.28 and 3307.31 of the Revised Code. Such contributions shall be received as specified in section 3307.14 of the Revised Code. A superannuate or other system retirant employed as a teacher is not a member of the state teachers retirement system, does not have any of the rights, privileges, or obligations of membership, except as provided in this section, and is not eligible to receive health, medical, hospital, or surgical benefits under section 3307.39 of the Revised Code for employment subject to this section.

(D) The employer that employs a superannuate or other system retirant shall notify the state teachers retirement board of the employment not later than the end of the month in which the employment commences. Any overpayment of benefits to a superannuate by the retirement system resulting from an employer’s failure to give timely notice may be charged to the employer and may be certified and deducted as provided in section 3307.31 of the Revised Code.

(E) On receipt of notice from an employer that a person who is an other system retirant has been employed, the state teachers retirement system shall notify the state retirement system of which the other system retirant was a member of such employment.

(F) A superannuate or other system retirant who has received an allowance or benefit for less than two months when employment subject to this section or section 3305.05 of the Revised Code commences shall forfeit the allowance or benefit for any month the superannuate or retirant is employed prior to the expiration of such period. The allowance or benefit forfeited each month shall be equal to the monthly amount the superannuate or other system retirant is eligible to receive under a single lifetime benefit plan of payment described in division (A) of section 3307.60 of the Revised Code. Contributions shall be made to the retirement system from the first day of such employment, but service and contributions for that period shall not be used in the calculation of any benefit payable to the superannuate or other system retirant, and those contributions shall be refunded on the superannuate’s or retirant’s death or termination of the employment. Contributions made on compensation earned after the expiration of such period shall be used in calculation of the benefit or payment due under section 3307.352 of the Revised Code.

For purposes of this division, “employment” does not include uncompensated volunteer work if the position is different from the superannuate’s or other system retirant’s position with the employer by which the superannuate or retirant was employed at the time of retirement.

(G) On receipt of notice from the Ohio police and fire pension fund, public employees retirement system, school employees retirement system, or Cincinnati retirement system of the re-employment of a superannuate, the state teachers retirement system shall not pay, or if paid shall recover, the amount to be forfeited by the superannuate in accordance with section 145.38, 742.26, or 3309.341 of the Revised Code or any requirement of the Cincinnati r etirement s ystem.

(H) If the disability benefit of an other system retirant employed under this section is terminated, the retirant shall become a member of the state teachers retirement system, effective on the first day of the month next following the termination, with all the rights, privileges, and obligations of membership. If the retirant, after the termination of the retirant’s disability benefit, earns two years of service credit under this retirement system or under the public employees retirement system, Ohio police and fire pension fund, school employees retirement system, or state highway patrol retirement system, the retirant’s prior contributions as an other system retirant under this section shall be included in the retirant’s total service credit, as defined in section 3307.50 of the Revised Code, as a state teachers retirement system member, and the retirant shall forfeit all rights and benefits of this section. Not more than one year of credit may be given for any period of twelve months.

(I) This section does not affect the receipt of benefits by or eligibility for benefits of any person who on August 20, 1976, was receiving a disability benefit or service retirement pension or allowance from a state or municipal retirement system in Ohio and was a member of any other state or municipal retirement system of this state.

(J) The state teachers retirement board may make the necessary rules to carry into effect this section and to prevent the abuse of the rights and privileges thereunder.
