Be it enacted by the Senate and House of Representatives
in General Court assembled, and by the authority of the same,
John Doherty, a teacher in the public school system of the city of Boston, while on leave of absence from his position as a teacher in said city for the purpose of acting as a full-time officer of the Boston teachers union, shall be considered, for the purposes of chapter thirty-two of the General Laws, to be on leave of absence without pay. Said John Doherty shall receive credit in the teachers retirement system for service from July first, nineteen hundred and seventy-one to June thitieth, nineteen hundred and seventy-five, inclusive. Said period of creditable service shall be dependent upon his contribution to the annuity savings fund of said teachers retirement system, the amount which he would have contributed to said fund had he remained in the service of the city of Boston as a teacher for the applicable period pursuant to subdivision (3) of section three of said chapter thirty-two. No retirement allowance under said chapter thirty-two shall become effective for said John Doherty until he has paid to the annuity savings fund of said teachers retirement system, a make-up payment, calculated with interest, for the amount equal to that which would have been withheld as regular deductions from his regular compensation.
