What is the ruling on working in a usurious bank in a department not dealing with usury due to the unavailability of other suitable work?

If your work in a usurious bank is in a department unrelated to usury and does not assist in it, then we hope there is no sin upon you for that.

Likewise, there is no harm upon you in moving alone to work in the distant company if it is within a travel distance and you are able to do so.
