Is it permissible to continue working with the usurious savings books at the Egyptian Post Office given the administrative intransigence that prevents transferring out of them?

Working in the field of savings accounts with usurious interest is impermissible, and its ruling is the same as working in usurious banks, which is prohibited. The questioner should request a transfer from this job. If she is unable to do so, it is not permissible for her to remain in it unless she is compelled to, such as not being able to find the minimum requirements for life for herself and those she supports. In this case, she may remain while searching for another job.
