21. The number of members that may be designated under the first paragraph of section 20 to represent the employees on a pay equity committee may not exceed 12.
If the application of the first paragraph of section 20 would cause their number to exceed 12, the mode of designation of the 12 members shall be determined by agreement between the employer and the employees or, failing agreement, by the Commission on the application of the employer, of a certified association or of an employee not represented by a certified association. In determining the mode of designation, the Commission shall take into account the number of employees represented by a certified association in relation to the number of employees not represented by a certified association, as well as the representation of predominantly female job classes and predominantly male job classes among those employees.
