Is working for a company specialized in the production of alcoholic beverages permissible or forbidden?

If your work in the second company is related to the production of alcoholic beverages, then it is not permissible for you to work there, because that involves assisting in the production of intoxicants. Allah has forbidden the consumption of alcohol and assisting in it, and the Prophet, peace and blessings be upon him, cursed ten categories of people related to alcohol. Do not seek provision through disobeying Allah; a little of what is lawful is better than much of what is unlawful.

It is not permissible for you to leave your work in your first company before the contract period ends or without the company's permission.
