The principal or head administrator invites the employee to a private meeting in writing to have a formal conversation to discuss the particular discipline matter. The meeting is between the principal or head administrator and the employee. After the meeting, the principal or head administrator will serve the employee with a First Warning that memorializes the meeting, the nature of the misconduct and sets forth the improvement needed. The First Warning shall be issued within ten school days of the meeting. If the employee disagrees with the First Warning, the employee may submit a written rebuttal, which shall be included in the employee’s disciplinary file and copied to the UNION, and which will be reviewable should the discipline be escalated to a Final Warning in Lieu of Suspension or dismissal decision.
