Louisiana Revised Statutes Tit. 17, § 1203. Pay deduction for tardiness

No teacher employed in the public schools shall suffer any loss or deduction of pay for tardiness, unless such tardiness has caused loss of time from official class duties, on more than two occasions and for a period of one hour or more, during any one school year. In all cases where deduction of pay may be made as herein provided, the amount of pay deducted shall be based on one day's pay proportioned to the period of tardiness. To definitely fix and establish the extent of time tardy, a teacher, upon request of his superior or principal, shall sign a slip stating the time of her arrival and reporting for duty; and if not requested so to do, he may voluntarily sign such slip and present it to the principal or superior.
