What is the ruling on a woman praying in front of men when she feels embarrassed and shy?

A woman is not permitted to work in a place where she mixes with men unless there is an urgent need. If there is such a need, it is permissible, provided she adheres to the complete hijab, avoids seclusion with a non-mahram man, and limits her speech with men to what is necessary, without suspicion or softening of speech. There is no harm for a woman to pray in front of men, provided she adheres to the legal hijab and is careful to cover herself.
