60i(1C) Where an employee is employed on a daily rate of pay or on piece rates, the ordinary rate of pay shall be calculated by dividing the total wages earned by the employee during the preceding wage period (excluding any payment made under an approved incentive payment scheme or for work done on any rest day, any gazetted public holiday granted by the employer under the contract of service or any day substituted for the gazetted public holiday) by the actual number of days the employee had worked during the wage period (excluding any rest day, any gazetted public holiday or any paid holiday substituted for the gazetted public holiday);
(1D) For the purposes of payment of sick leave under section 60F, the calculation of the ordinary rate of pay of an employee employed o a daily rate of pay or on piece rate under subsection (1C) shall take account only of the basic pay the employee receives or the rate per piece he is paid for work done in a day under the contract of service
