Recent question answered on working a supermarket where they sell alcohol
السلام عليكم ورحمة اللهِ وبركاته
Whilst Working for a non Muslim who sells alcohol as part of his business or haram meat, it is permissible in shariah for you to handle it for selling e.g. at a checkout etc, as part of your employment with the non Muslim. Non muslims are ghayr mukallaf and not bound by shariah and since you are employed by the non Muslim, you are obliged to do whatever the owner requests. As long as the selling of alcohol is not the main business.
You are not profiting from the sale of the alcohol/haram but are simply handling it as part of your employment duties.
This is the position of Imam Azam Abu Hanifa.
