Life is duress, we all get stuck in things we don’t want to do. But that doesn’t change the fact that a person CAN get other work, maybe worse work, maybe they have to move, maybe cheaper, but it’s out there. Your relationship with your employer IS voluntary, you said yes to that wage. Nothing immoral about it. Especially in the 21st century, we don’t have indentured servitude anymore.
Deuteronomy 24:15
Pay them their wages each day before sunset, because they are poor and are counting on it. Otherwise they may cry to the Lord against you, and you will be guilty of sin.
1 Samuel 12:3
Here I stand. Testify against me in the presence of the Lord and his anointed. Whose ox have I taken? Whose donkey have I taken? Whom have I cheated? Whom have I oppressed? From whose hand have I accepted a bribe to make me shut my eyes? If I have done any of these things, I will make it right.”
Malachi 3
“Then the offering of Judah and Jerusalem
Will be pleasant to the Lord,
As in the days of old,
As in former years.
5 And I will come near you for judgment;
I will be a swift witness
Against sorcerers,
Against adulterers,
Against perjurers,
Against those who exploit wage earners and widows and orphans,
And against those who turn away an alien—
Because they do not fear Me,”
Says the Lord of hosts.
