What is the ruling on my fiancée working in a field where she constantly and for long periods intermingles with men, and she may be alone with a man or a group of men in an office with an open door? Is this considered forbidden intermingling (ikhtilat muharram) or seclusion (khalwa)? What is the ruling on my jealousy towards her in these situations? And is it permissible for me to revoke my agreement with her regarding her work and request another job where there isn't this degree of intermingling, knowing that she needs to work to provide a decent life for her children, even though my work provides them with the necessities?

A woman's work is permissible if it is religiously lawful, provided she adheres to Islamic guidelines, such as avoiding prohibited mixing or private seclusion (khalwa). There is mixing that is prohibited (if suspicion usually cannot be averted) and mixing that is permissible. A woman's conversation with a non-mahram man is permissible when there is a need, with due observance of Islamic manners. If the work involves something prohibited, then it is not permissible to continue in it except out of necessity or severe need. The recreational life of children is not considered a justification for prohibited work. It is preferable for a woman to avoid working in places where men are present. A husband's jealousy over his wife is required and should be moderate. It is the husband's right to prevent his wife from working, and if the marriage has not yet taken place, he can stipulate that she leaves her work. Agreeing with her to work is not religiously binding if the work leads to something prohibited.
