In office or under a compelled helpless situation is it allowed to work and communicate with non-Mehrem?
الجواب حامدا و مصلیا
In a dire necessity it is allowed to communicate to the extent of necessity with non-Mehrem females. Similarly, it is allowed to work in an office where non-Mehrem females work and the females should try to observe Hijab to the possible extent, and the males should abstain to be in solitude with them.
Allah knows best.
