Section 18 Apportionment of remuneration
Where for any period a worker receives remuneration for work for part of which he is entitled to statutory minimum remuneration at one or more time rates and for the remainder of which no statutory minimum remuneration is fixed, the amount of the remuneration which is to be attributed to the work for which he is entitled to statutory minimum remuneration shall, if not apparent from the terms of the contract between the employer and the worker, be deemed for the purposes of this Part of this Act to be the amount which bears to the total amount of the remuneration the same proportion as the time spent on the part of the work for which he is entitled to statutory minimum remuneration bears to the time spent on the whole of the work.
