You shall not defraud a poor and needy hired servant, whether he be one of your own countrymen or one of the aliens who live in your communities. You shall pay him each day’s wages before sundown on the day itself, since he is poor and looks forward to them. Otherwise he will cry to the Lord against you, and you will be held guilty.
Deuteronomy 24: 14-15
You shall not withhold overnight the wages of your day laborer.
Behold the wages you withheld from the workers who harvested your fields are crying aloud, and the cries of the harvesters have reached the ears of the Lord of hosts.
Woe to him who makes his neighbors work for nothing, and does not give them their wages…
Institutions in host countries must keep careful watch to prevent the spread of the temptation to exploit foreign laborers, denying them the same rights enjoyed by nationals, rights that are to be guaranteed to all without discrimination…Immigrants are to be received as persons and helped, together with their families, to become part of societal life. In this context, the right of reuniting families should be respected and promoted.
Compendium of the Social Teaching of the Church
Everyone should be able to draw from work the means of providing for his life and that of his family, and of serving the human community.
