Does working for a government institution that provides general insurance services, deals with interest-bearing loans, imposes fines for late payment of installments and subscriptions, and invests in both permissible and impermissible matters (such as hotels that serve alcohol and usurious dealings with banks) make earning money from it unlawful?

Working in cooperative insurance companies is permissible, unlike commercial ones. An institution that lends to retirees with interest, or imposes fines for late payment of installments or loans, deals with forbidden usury, and it is not permissible to assist it. It is not permissible to invest money in hotels that contain alcohol bars, or to contribute to a usurious bank. If your work is limited to the permissible, there is no harm in continuing it; otherwise, it is not permissible to continue it except by moving to a department free from the forbidden.
