Deuteronomy 24:14,15

Not oppress a hired servant By detaining his wages from him when due, which is the meaning of oppression here, as appears from the next verse. At his day thou shalt give him his hire That is, at the time appointed, weekly or daily. He speaks of a hireling who was so poor as not to be able to provide himself and family with necessaries without his wages, and who therefore eagerly expected them as the support of their lives.
