Beacuse if I work in a women only environment i will be able to open my niqab if it gets hot, I will not be forced to comunicate and work togehter with men wich I personaly dont like.

I think its a matter of personality. Im know that women with niqab works in mixed environment. But me personaly would feel more comfortable in a place for only women =)

And like my mom use to say. If you don't ask, you will never know. :)
