Is a lawyer, who is compelled to win cases against employees who have rights, sinful, knowing the injustice of the employer, due to fear of losing his job?

Advocating for falsehood and causing employees to lose their rights is forbidden (haram), and one must repent from it. It is not permissible to return to it, even if it leads to losing one's job. Advocating without right is a forbidden act, and its earnings are unlawful. It is divided into two types: advocating for the truth, which is permissible, and advocating for falsehood, which is forbidden due to its nature of cooperating in sin and aggression.
