2.7.1 The association and TEBA may at any time agree to negotiate revisions to the central points of the collective agreement. These changes will come into effect from the date the association and TEBA agree. 7.1.5 The association may, upon request, meet with the Superintendent of Human Resources or the designated representative to discuss concerns about the plans that apply to the plans covered by this agreement. 1.1 This collective agreement applies to any person who requires a teacher`s certificate as a condition of employment on the Board of Directors, with the exception of positions that have been agreed to be excluded from local negotiations between the Board of Directors and the association. 4.5.1 Subject to paragraphs 4.5.2, 4.5.3, 4.5.4, 4.5.9, 4.5.10, 4.5.11, 4.5.12 and 17.1.1 of this Agreement, all appointments and appointments will be continued, unless the Board of Directors is withdrawn in accordance with this agreement and the School Act (RSA 2000). b) TEBA and the association may agree to proceed with an arbitration board composed of a single arbitrator instead of a three-member arbitration board. In this case, TEBA and the association designate, within fifteen days of operation, the designation of a person as a single arbitrator with a single arbitrator. If it is not possible to agree on the person as a single arbitrator, each party may request in writing that the Director of Mediation Services indicate the required appointment. 1.1 This letter of appeal is made in accordance with Article 8 of the collective agreement (practical conditions). The parties agree that when teachers` teaching time is compressed and current collective agreements are tacit, teachers are given a break from the extra time provided in the table below. The next 0.25 days are rounded for this calculation. Both parties recognize that flexibility is needed to maintain the board schedule, but also to assure teachers that an extension of teaching days can result in a break for teachers.
