15. The pensionable salary of a teacher who simultaneously holds more than one pensionable employment in a year is the aggregate of the salary paid to him for all such employments if the total service credited to him in respect of such employments is equal to one year or less.
If the total service credited in respect of the pensionable employments of the teacher is reduced by the application of section 17, the pensionable salary of the teacher shall not exceed the salary attached to the employment he holds for a proportionately greater number of days in the year or, if he holds such employments for porportionately the same number of days, the salary attached to the highest paid employment. The days and parts of a day of a maternity leave credited pursuant to section 19 shall not be taken into account to determine the number of days referred to above.
For the purposes of the second paragraph, the salary attached to an employment is the salary defined in section 11, computed on a yearly basis and multiplied by the total service credited, excluding service credited pursuant to section 19.
