Is money earned from working in a hotel that serves alcohol considered permissible (halal), especially if a portion of the salary comes from alcohol revenues? And must this portion be given away in charity? What is the ruling on money obtained from health and social insurance services and tips under such circumstances?

Working in this hotel is unlawful (haram (definition)) due to its involvement in cooperation in sin and aggression. It is impermissible to remain in it except out of necessity, which means that the worker cannot find food, clothing, or shelter for himself and his dependents, or cannot find another job, even if it is for a lower wage.
