4. Pensions. Any public employee who is a member of any pension or retirement system may elect, while on military duty, to contribute to such pension or retirement system the amount which he would have contributed had his employment been continuous and upon making such contribution he shall have the same rights in respect to membership in the retirement system as he would have had if he had been present and continuously engaged in the performance of the duties of his position.
Time during which a member is absent on military duty shall not constitute an interruption of continuous employment, but such time shall not be counted or included in determining the length of total service unless such member contributes to the retirement system the amount he would have been required to contribute if he had been continuously employed during such period. Such contribution, or any part thereof, may be paid at any time and from time to time, while in military duty, or within five years after the date of his restoration to his position or before December thirty-first, nineteen hundred sixty-two, whichever date is later, or in the event of the death of the member while in military duty such contribution, or any part thereof, may be paid by the named beneficiary or the legal representative of the member's estate within one year following proof of such death. A member of the New York state employees' retirement system or of the New York state policemen's and firemen's retirement system, other than a member of the state police in a collective negotiating unit established pursuant to article fourteen of the civil service law, who is in the employ of the state on March thirty-first, nineteen hundred seventy, who failed to make such contributions during the prescribed period of time may nonetheless obtain credit for time during which he was on military duty by depositing with such retirement system an amount equal to the contribution he would have made had he made a timely election, with regular interest, on or before March thirty-first, nineteen hundred seventy-two, provided, however, such member may elect to deposit such amount over a period of time no greater than the period for which credit is being claimed, in which case such payments must commence no later than March thirty-first, nineteen hundred seventy-two. If the full amount of such payments is not paid to the retirement system, the amount of service credited shall be proportional to the total amount of the payments made. A member of the New York state policemen's and firemen's retirement system who is a member of the state police in a collective negotiating unit established pursuant to article fourteen of the civil service law, who is in the employ of the state on March thirty-first, nineteen hundred seventy-one, who failed to make such contributions during the prescribed period of time may nonetheless obtain credit for time during which he was on military duty by depositing with such retirement system an amount equal to the contribution he would have made had he made a timely election, with regular interest, on or before March thirty-first, nineteen hundred seventy-two, provided, however, such member may elect to deposit such amount over a period of time no greater than the period for which credit is being claimed, in which case such payments must commence no later than March thirty-first, nineteen hundred seventy-two. If the full amount of such payments is not paid to the retirement system, the amount of service credited shall be proportional to the total amount of the payments made.
A member of the New York state teachers' retirement system, whose service terminates on the expiration of his contract, and for whom there is no employer to cover the cost of his accruing pension rights while in military service following the cessation of his contract, may pay in addition to his own contributions, an amount equal to the percentage of his salary which his employer would have paid had he remained under contract, which contributions shall be paid into the pension accumulation fund of the aforementioned retirement system and be treated as if they had been continued by his employer except that in the event of his death as a member prior to retirement or on his withdrawal of his accumulated contributions from the system, the amounts so paid by him shall be returnable, with regular interest, as if they were a part of his accumulated contributions. Such contributions or any parts thereof may be paid at any time and from time to time while in military duty or within five years after the member has returned to public school teaching in New York state or before December thirty-first, nineteen hundred sixty-two, whichever date is later.
Any such member, while on military duty, or his beneficiary, as the case may be, shall be entitled to all benefits of the retirement system of which he is a member except accidental disability retirement and accidental death benefit.
Any public employee holding a position by appointment who is or was a member of any pension or retirement system and who, while such member and while on military duty, applied for retirement as a member of such system to take effect within thirty days prior to the date of expiration of his appointment and who shall accordingly have been retired pursuant to such application but thereafter and within thirty days after the effective date of such retirement shall have been reappointed to his said position and shall have applied thereafter, before or upon his release from military duty, for membership in such pension or retirement system, shall be deemed to have had continuous membership in such pension or retirement system and shall be entitled to all the rights, benefits and privileges under his contract of membership as it existed at the time of such retirement, provided he shall (1) return any pension, annuity and retirement allowance payments received by him during the period of such retirement, (2) consent to the termination of his right to receive pension, annuity or retirement allowance payments on the basis of such retirement, (3) pay into the appropriate fund of such pension or retirement system the amount he would have contributed thereto, if he had not so retired, on the basis of the salary he was receiving when he so retired, and (4) pay into the appropriate fund of such pension or retirement system the amount which his employer would have paid thereto on his account if he had continued as a member during such period of retirement.
