18. The pensionable salary of an employee 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 employee is reduced by the application of section 20, the pensionable salary of the employee shall not exceed the salary attached to the employment held for a proportionately greater number of days in the year or if he holds such employments for proportionately 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 22 shall not be taken into account for determining 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 14, computed on a yearly basis and multiplied by the total service credited, excluding service credited pursuant to section 22.
