9.3.5 Teacher commitment: a teacher on intermediate professional improvement leave enters into an agreement with the department to restore service at the end of the leave and cannot resign or leave the magisterium, except by mutual agreement between the department and the teacher, for a period of at least two (2) years after the return to work. 2.1 The duration of this collective agreement is from September 1, 2018 to August 31, 2020. Unless otherwise stated, this collective agreement is fully applicable until 31 August 2020. 1.2 For the purposes of this collective agreement, and notwithstanding the provisions of the Schools Act, Teachers` Day is considered non-compulsory. 3.4.11 Clauses 3.4.6 to 3.4.10 of this article apply only to teachers whose recruitment date is set at or after this Agreement comes into force. 5.3.1 A substitute usually follows the teacher`s program that is not in office. The school administration may request a change in the schedule and accept a substitute teacher. Otherwise, the administration may require a substitute teacher to adapt to the adjustments that can normally occur when the absent teacher is present. 2.4.1 Notwithstanding paragraph 59, paragraph 2 of the Labour Code, a notice of opening of local negotiations by a department or association, after 60 days from the end of the collective agreement under Section 11, paragraph 4, of the PECBA, must be attributed to the collective agreement or settle the essential conditions by other means. (c) the parties may, in a particular case, accept an alternative arbitrator and complete or remove the list of arbitrators by mutual agreement.

l) For the purposes of this process, calendars reflect calendar days, with the exception of Saturdays and Sundays or public holidays. However, the parties may extend the deadlines by mutual agreement and such a request for an extension of time is not rejected inconsistently. The arbitrator has the power to extend the deadlines in agreement with the parties. This procedure will come into force at the time of signing and will no longer have any force and effect once all collective agreements that begin on September 1, 2018 between the association and the school departments have been ratified.
