Classifications for New Positions. Whenever a new classification is created for a new position, the parties will negotiate for its exclusion or inclusion in this agreement, and if included rate of pay. All such negotiations will be handled by the union-management committee. The employer retains the right to set a temporary rate of pay and to post and fill the position temporarily, pending the completion of the above requirement. The rate of pay when finally decided will be retroactive to the date of the position being filled.
