What is the ruling on working as an accountant for a contracting company that deposits its money in banks?

If the bank is usurious and the company is not compelled to deposit funds in it due to the availability of Islamic alternatives, and depositing money in this bank is part of your work, then it is forbidden because it contributes to what is unlawful. However, if the company is compelled to deposit funds in a usurious bank due to the absence of Islamic banks, and the account is a current account, then there is no blame upon you.
