karṣaṇavaidehakā vā sasyapaṇyārambhaparyavasānāntare sannasya yathākṛtasya karmaṇaḥ pratyaṃśaṃ dadyuḥ //

Cultivators or merchants shall, either at the end or in the middle of their cultivation or manufacture, pay to their labourers as much of the latter's share as is proportional to the work done. If the labourers, giving up work in the middle, supply substitutes, they shall be paid their wages in full.
