Are unmarried Jewish women allowed to work? (Volunteer or not volunteer, paid or unpaid) Why or why not? Please provide your sources accordingly. Please also provide which sects (if they are multiple sects) follows these rules and which sect (if they are multiple) does not. I would please like the “Traditional Orthodox” (to use a phrase from the RAA: https://rabbinicalalliance.org/) opinion. Thank you in advanced.
Q: If a girl is offered a well-paying job in a gentile company, can she take it?
A: It depends on the circumstances. Are there enough frum workers around her? Will she be subject to the influence of the males of low character who work there and are around her? How much does she need the job? Without knowing the answers to these questions – and other questions as well – nobody can give you a true answer. Without knowing the girl and having an understanding of these factors, I couldn’t tell you.
This needs special private instruction from people who know her well and know the circumstances. פרנסה is very important, but a job like that can easily ruin a woman. And therefore, it needs thoughtful deliberation by someone who knows the girl.
Unmarried women are absolutely allowed to work. This is obvious to the point that it does not have to be stated. The Talmud does say that until age 12, the earnings belong to her father. But after age 12 or if her father dies, she can keep the earnings for herself, even if the brothers support her.
