Is it permissible for a woman to continue working in an internet cafe frequented by men who sometimes view impermissible websites and images?

It is not permissible to work in an internet cafe unless it adheres to Sharia controls, which prevent viewing forbidden things, prevent mixing and seclusion between the sexes, and prevent the squandering of prayer times. If these controls are not met, then it is not permissible for a woman to continue in this work.
