What is the ruling on working as a manager of files for employees applying for loans, knowing that the loan funds are collected in a housing fund at a usurious bank, and the company imposes a 1% deduction from the loan value for the employee's participation in the deceased's exemption system?

There is no objection to your work as an employee file manager and reviewer of their eligibility for loans, because your work is not related to the company depositing a percentage from the employee into an interest-based bank. There is no blame on whoever does not directly commit what is forbidden, nor directly or intentionally assists in it. It is advisable to counsel those in charge to cease saving in interest-based banks and to turn to Islamic banks. As for what is deducted from the loan for participation in a system to exempt workers in case of death, if it is a cooperative, takaful insurance, then there is no objection to it; otherwise, it is not permissible.
