ANSWER:

You must not jeopardize your Islam for anyone. It is not permissible for women to work or study in mixed environments. Simply refuse in working in a mixed environment and ask them to get you married if you are a burden on them. 

My father does not take care of me and I have become the responsability of my brothers. Unfortunatly they see me as a burden now. They keep pushing me to go find a job. The problem is that I live in France and I’ll have to work without hijab and with mens. What should I do ?
