The Board of Trustees of the Alabama Institute for Deaf and Blind shall grant personal leave to any teacher employed by said board up to five days annually, noncumulative, during the time schools are in session. Two days of personal leave shall be granted upon request of the teacher with full pay and three days may, at the discretion of the school's board, be granted with part pay or with full pay. The teacher shall whenever possible, notify the board five days in advance of the time such leave is to be taken; however, when such notice is not practical, leave may be taken in the same manner and under the procedures governing sick leave.
