I work in the administrative department of a bank in (REMOVED), where the shares of the bank are owned by Non muslims. The role involves dealing with clients pension and investments account, from an interest perspective, the clients do earn interest. My role is just actioning request, closing accounts and sometimes applying the interest onto the account. Considering the above. is there any sharia issues in working in the bank

Q1899. What is the ruling in the matter of working in banks that deal with ribā, especially if there are no other jobs to do?
A: If the work in the bank is, in any way, related to ribā-based transactions, it is not permissible. However, the claim that no other ḥalāl employment by which to earn a living is available is not a valid reason to dabble in ḥarām business.
