7.—(1) Any worker employed in agriculture on piece work for which no minimum piece rate has been fixed, or any person authorised by such a worker, may complain to the Board that the piece rate of wages paid to the worker for that work is such a rate as would yield in the circumstances of the case to an ordinary worker a less amount of wages than the minimum rate for time work applicable in the case of that worker.
(2) The Board, on the receipt of a complaint under paragraph (1) and after giving to the employer an opportunity of making such representations as he thinks desirable, may direct that the employer shall pay to the worker such additional sum by way of wages, for any piece work done by the worker at that piece rate at any time within fourteen days before the date of the complaint or at any time after the date of complaint and before the decision of the Board thereon, as in its opinion represents the difference between the amount which would have been paid if the work had been done by an ordinary worker at the minimum rate for time work and the amount actually received by the worker by whom or on whose behalf the complaint is made.
(3) Any sum directed by the Board under paragraph (2) to be paid shall be a debt recoverable summarily by or on behalf of the worker from the employer.
