All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His Slave and Messenger.
The woman has the right to manage her wealth as she sees it to be in her interest, and there is nothing wrong with preventing someone, whether her husband or another, from working in her company if she fears harm from them. The husband has no right to be angry with his wife for this and blame her for not allowing him to work.
However, the wife should be wise in dealing with her husband's desire to work in her company. She can advise him and help him quit drinking alcohol by reminding him of the benefits of repentance for both religious and worldly matters. Communication and mutual understanding are essential in such situations to maintain a harmonious relationship.
Allah knows best.
