My little brother (removed) wants to do a job during his vacation. In our country you have 2 choices, working in the supermarkt (selling food etc.) or in stores where they sell everything including clothes, food, kitchen suplies etc but in these stores you have to work really hard while you earn very little. While working in the supermarkt one is earning enough money. Is it haram to work in a supermarket where they sell also alcohol, pork etc..?
One should not work in the department or section of the store where they sell haram. He should not be a cashier or a bagger of the groceries that are haram either. Perhaps he can work in the produce section for example where no haram is involved.
