37. The seniority accumulated by an employee in an institution before the date on which the clauses negotiated and agreed at the local or regional level come into force is recognized up to one year per period of 12 months.
With respect to employees that were not represented by a certified association of employees, seniority is deemed to have been accumulated according to the provisions of the collective agreement of the newly certified association of employees.
Seniority lists must be posted within 30 days after the date of the end of the pay period that includes the date of coming into force of the clauses negotiated and agreed at the local or regional level. The periods for posting information and the seniority correction procedures set out in the collective agreement determined for the newly certified association of employees under section 36 apply.
However, the institution and the newly certified association of employees may agree to a date for integrating seniority lists that is earlier than the date provided in the third paragraph for matters negotiated and agreed at the local or regional level that are the subject of an agreement.
