(1) Notwithstanding any other provision of the law to the contrary, should an age or service retirant return March 1, 1986, or later to employment in a position covered by the firemen's relief and pension fund from which he or she retired, no pension payments shall be paid to him or her for the period of the reemployment, and he or she shall make member contributions to the firemen's relief and pension fund as if he or she were an active member during the reemployment.
(2) If reemployment terminates before the retirant has rendered sufficient reemployment to accumulate at least three (3) years of credited service had he or she been an active member during the reemployment, the payment of his or her pension shall resume upon termination, under the form of payment in force at the beginning of reemployment and in an amount as it would be had he or she not been reemployed.
(3) If reemployment continues until the retirant has rendered sufficient reemployment to accumulate at least three (3) years of credited service, then effective upon completion of reemployment, his or her retirement shall be recalculated to account for the additional accrued service credit and salary.
