What is the ruling on working as an administrative manager in a commercial marketplace that sells alcohol and pork, and what is the ruling concerning the years prior to that, knowing that the person in question does not currently deal directly with them?

The basic principle regarding a person's work as a business or general manager for a permissible market is that it is allowed. However, if the work involves prohibitions such as selling alcohol or pork, or dealing with riba (interest), and the manager has no authority to change these prohibitions, or if his work assists in bringing them about or promoting them, then it is not permissible for him to remain in this job. He must seek other employment.
